I am trying to capture the filename of an uploaded file via a wtforms FileField
in my validator
def checkfile(form,field):
print form
print field
the 'print forms' statement shows: forms.ticket.TicketForm object at 0x1d2a350
the 'print fields' statement shows: input id="files" name="files" type="file"
if i try to access field.file or field.files i get the error: 'FileField' object has no attribute 'file(s)'
field.data is empty
so how can i access the filename to run a validator?
relevant portion of my class:
class MyForm(wtforms.Form):
files = wtforms.FileField('Files',[checkfile])
which is rendered in my template as:
<form enctype="multipart/form-data" class="form-horizontal" name="add_ticket" action="/ticket/add" method="post">
<input type="hidden" name="_xsrf" value="xxxxxxxxxx"/>
<input class="input-medium" id="files" name="files" type="file">
</form>

I am programming in Spring and using Thymeleaf as my view, and am trying to create a form where users can update their profile. I have a profile page which lists the user's information (first name, last name, address, etc), and there is a link which says "edit profile". When that link is clicked it takes them to a form where they can edit their profile. The form consists of text fields that they can input, just like your standard registration form.
Everything works fine, but my question is, when that link is clicked, how do I add the user's information to the input fields so that it is already present, and that they only modify what they want to change instead of having to re-enter all the fields.
This should behave just like a standard "edit profile" page.
Here is a segment of my edit_profile.html page:
First Name:
Here is the view controller method that returns edit_profile.html page:
#RequestMapping(value = "/edit", method = RequestMethod.GET)
public String getEditProfilePage(Model model) {
model.addAttribute("currentUser", currentUser);
System.out.println("current user firstname: " + currentUser.getFirstname());
model.addAttribute("user", new User());
return "edit_profile";
}
currentUser.getFirstname() prints out the expected value, but I'm getting blank input values in the form.
Thanks.
Solved the problem by removing th:field altogether and instead using th:value to store the default value, and html name and id for the model's field. So name and id is acting like th:field.
I'm slightly confused, you're adding currentUser and a new'd user object to the model map.
But, if currentUser is the target object, you'd just do:
<input type="text" name="firstname" value="James" th:value="${currentUser.firstname}" />
From the documentation:
http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html
I did not have a form with input elements but only a button that should call a specific Spring Controller method and submit an ID of an animal in a list (so I had a list of anmials already showing on my page). I struggled some time to figure out how to submit this id in the form. Here is my solution:
So I started having a form with just one input field (that I would change to a hidden field in the end). In this case of course the id would be empty after submitting the form.
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:field="*{id}" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
The following did not throw an error but neither did it submit the animalIAlreadyShownOnPage's ID.
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:value="${animalIAlreadyShownOnPage.id}" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
In another post user's recommended the "th:attr" attribute, but it didn't work either.
This finally worked - I simply added the name element ("id" is a String attribute in the Animal POJO).
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:value="${animalIAlreadyShownOnPage.id}" name="id" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
I'm using Spring+Thymeleaf to see and modify the users in a database. I would like to set the input fields to the actual values of an original user but I've tried with different styles and it doesn't work.
With the present configuration I can update information of users and see the id of original user (it's not in a input field) but I can't show the actual configuration in input field as default.
CONTROLLER:
#GetMapping(value = {"/", ""})
public String subusersPage(HttpSession session, Model model) {
String idUser = BaseController.getLoggedUser(session);
UserDTO userDTO = userService.getUserById(idUser);
model.addAttribute("subusersDTO", userService.getSubusersDTO(userDTO.getSubusers()));
model.addAttribute("populations", userDTO.getPopulations());
model.addAttribute("configurations", userDTO.getConfigurations());
model.addAttribute("attributes", userDTO.getAttributes());
model.addAttribute("subuserDTO", new SubuserDTO());
return "subusers";
}
HTML:
<th:block th:each="subuserDTO_original : ${subusersDTO}">
<hr>
<form action="#" th:action="#{/subusers/__${subuserDTO_original.id}__}" th:object="${subuserDTO}" method="post">
<div>
<p th:text="${'Id: ' + subuserDTO_original.id}"></p>
<p>Name: <input type="text" th:field="*{name}" th:name="name" th:value="${subuserDTO_original.name}"/></p>
<p>Population: <input type="text" th:field="*{population}" th:name="population" th:value="${subuserDTO_original.population}"/></p>
<p>Configuration: <input type="text" th:field="*{configuration}" th:name="configuration" th:value="${subuserDTO_original.configuration}"/></p>
<p>Attributes: <input type="text" th:field="*{attributes}" th:name="attributes" th:value="${subuserDTO_original.attributes}"/></p>
<p>
<button type="submit" th:name="action" th:value="update">Update</button>
<button type="submit" th:name="action" th:value="delete">Delete</button>
<button type="reset" th:name="action" th:value="clear">Clear</button>
</p>
</div>
</form>
<form action="#" th:action="#{/subusers/__${subuserDTO_original.id}__}" method="get">
<button type="submit">Default</button>
</form>
</th:block>
Any help will be very appreciated, thank you!
If you want to edit an existing user, then your th:object (which is ${subuserDTO} in this case) needs to be populated with the values of the original user. This is because when you use the attribute th:field="*{name}", it actually overwrites the name, id, and value of the html tag (which is why th:value="${subuserDTO_original.name}" isn't working.
Two other options you could do:
You could also set name="name" and use th:value instead.
Or another option, you could use ${subuserDTO_original} as your th:object.
I have a typical updateUser form built with Thymeleaf + Spring. I can list the user roles but I am trying to put these into a selectbox component. I am struggling with this line th:selected="${user.hasRole(role.role)}". Now, I know this component works and that is only a matter of access a boolean function to enable it. I am trying to reference a function of the form object using the select th:object. My syntax doesn't work. I have also try to access that function just like previous input tags would (only using the name without the object itself .ie username or in this case hasRole(). That doesn't work either.
<form th:object="${user}"
th:action="#{'/admin/usermanagement/adduser'} " method="post">
<div class="row">
<div class="col-md-3 form-group">
<label>Username:</label> <input type="text" class="form-control"
th:field="*{username}" />
</div>
</div>
<div class="col-md-3">
<h5>Roles :</h5>
</div>
<select class="js-example-basic-multiple" style="width: 75%"
name="froles" id="froles" multiple="multiple">
<option th:each="role : ${roles}" th:value="${role.role}"
th:selected="${user.hasRole(role.role)}"
th:text="${role.role}"></option>
</select>
<button type="submit" class="btn btn-primary">Submit</button>
In fact, my problem is types. th:selected="${user.hasRole(role.role)}" is a string and should be th:selected="${user.hasRole(role)}". I have both method in the domain object so that is fine.
th:value="${role.role}" is wrong for persistence. I want to return role but I get the following error message when I use role.role
codes [user.roles,roles]; arguments []; default message [roles]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.List' for property
and Java null exception when I use "${role}"
I have the following content in my HTML which is using Thymeleaf
<form action="#" th:action="#{/shutDown}" th:object="${ddata}" method="post">
<span>Domain</span>
<span th:text="${domain}" th:field="*{domain}">domain</span>
<input type="Submit" value="close" />
</form>
And I have the following in my Controller which is using Sprint Boot
#RequestMapping(value = "/shutDown", method = RequestMethod.POST)
public ModelAndView shutDownPage(ModelAndView modelAndView, Authentication authentication,
#ModelAttribute("ddata") DInputBean dInputBean) {
String domain = dInputBean.getdomain();
return modelAndView;
}
I'm hoping I'd get value of domain from the HTML in the Controller but it's always null. DInputBean has getters and setters for "domain" field.
The th:field attribute can be used on <input>, <select>, or, <textarea>.
A solution you could possibly replacing you second <span> with a hidden input element.
<form action="#" th:action="#{/shutDown}" th:object="${ddata}" method="post">
<span>Domain</span>
<input type="hidden" th:field="*{domain}" th:value="${domain}" />
<input type="Submit" value="close" />
</form>
If you wanted to keep the second div, just place the <input type="hidden"> inside the second <span> and remove the th:field attribute from the second <span>.
Edit:
If you wanted to add the value of domain in a span.
<form action="#" th:action="#{/shutDown}" th:object="${ddata}" method="post">
<span>Domain</span>
<span th:text="${domain}">domain<span>
<input type="hidden" th:field="*{domain}" th:value="${domain}" />
<input type="Submit" value="close" />
</form>
http://www.thymeleaf.org/doc/tutorials/3.0/thymeleafspring.html#inputs
An option is to use a read-only input field:
<input type="text" th:field="*{domain}" th:value="${domain}" readonly="readonly"/>
This both displays the value and sends it on submit.
The key is to add the value of the domain variable to the form:
#GetMapping("/shutDownPage")
public String shutDownPage(Model model) {
model.addAttribute("ddata" new Ddata()); //or however you create your bean
String username = ... //however you get your username
String domain = myRepositoryService.findDomainByUsername(username);
model.addAttribute("domain", domain);
return "shutDownPage";
}
Include an HTML page in the action so that when you open the HTML page in a browser without a server/container, the button will still appear to work:
<form action="confirmationPage.html" th:action="#{/shutDown}" th:object="${ddata}" method="post">
<!-- You can benefit from using a conditional expression -->
<span th:text="${domain != null ? domain : 'No domain supplied'}">[domain]</span>
<input type="hidden" th:field="*{domain}" th:value="${domain}"/>
<input type="Submit" value="close"/>
</form>
And your post method:
#PostMapping("/shutDown") //use shorthand
public String shutDownPagePost(#ModelAttribute("ddata") DInputBean dInputBean {
String domain = dInputBean.getDomain();
//do whatever with it
return "confirmationPage";
}
I'm building the website based on Joomla 3. I need to disable the validation of the fields: name, username, password1 (the second, because the first is password2) and email2 and use email1 as username (I installed the plugin Email for user authorization).
I have tried to remove these fields in file components/com_users/models/forms/registration.xml but the validation is still remaining. If I don't remove them but only change the rows required="true" to false for these fields the registration doesn't work at all and any user stored in the DB. How can I disable these fields?
It's not an easy workaround, and you will need some basic knowledge of Joomla and PHP, but I'll try to explain it to you as simple as i can.
>>> Creating view template override
First of all you will need to create your Registration view template override (to keep it Joomla update proof). To do so, create folder /templates/YOUT_TEMPLATE/html/com_users/registration and copy /components/com_users/views/registration/tmpl/default.php file there.
From now on you can modify registration output in your template folder.
>>> Modifying registration form output
By default Joomla takes all fields from form file /components/com_users/models/forms/registration.xml, where they are defined, and outputs them in a view. But if we don't want to use ALL the fields, we need to output fields manually.
My example code only output E-mail and Password fields for registration. Here's a sample code to do so: (default.php file)
<?php
defined('_JEXEC') or die;
JHtml::_('behavior.keepalive');
?>
<div class="grid_8" id="register_block">
<div class="content_block">
<h1>Registracija</h1>
<div class="login<?php echo $this->pageclass_sfx?>">
<form id="member-registration" action="<?php echo JRoute::_('index.php?option=com_users&task=registration2.register'); ?>" method="post" enctype="multipart/form-data">
<div>
<div class="login-fields">
<label id="jform_email1-lbl" for="jform_email1">E-mail:</label>
<input type="text" name="jform[email1]" id="jform_email1" value="" size="30">
</div>
<div class="login-fields">
<label id="jform_password1-lbl" for="jform_password1">Password:</label>
<input type="password" name="jform[password1]" id="jform_password1" value="" autocomplete="off" size="30">
</div>
<button type="submit" class="button"><?php echo JText::_('JREGISTER');?></button>
<input type="hidden" name="option" value="com_users" />
<input type="hidden" name="task" value="registration2.register" />
<?php echo JHtml::_('form.token');?>
</div>
</form>
</div>
</div>
</div>
Please note, that I've also replaced task value from registration.register to registration2.register, I did this to bypass some of validation rules using my own controller.
>>> Creating controller override
Locate file /components/com_users/controllers/registration.php and create a copy of it called registration2.php in same folder.
Open file registration2.php and change It's class name from UsersControllerRegistration to UsersControllerRegistration2
From now on Joomla registration form will use this class to create a new user.
Find a method called register and find this line:
$requestData = JRequest::getVar('jform', array(), 'post', 'array');
This is where Joomla get's registration form data. Add the following lines:
$requestData['name'] = $requestData['email1'];
$requestData['username'] = $requestData['email1'];
$requestData['email2'] = $requestData['email1'];
$requestData['password2'] = $requestData['password1'];
It will add missing registration info, and help you pass validation.
NOTE: This is a sample code, to show the main logic. If anyone has a better solution, I'd be more than happy to hear it.
Following same idea, a simpler solution might be just including hidden inputs with values in com_users\views\registration\tmpl\default.php above
<button type="submit" class="btn btn-primary validate"><?php echo JText::_('JREGISTER');?></button>
add
<input type="hidden" id="jform[username]" name="jform[username]" value="username" />
<input type="hidden" id="jform_name" name="jform[name]" value="name" />
It would pass the validation and you would no longer need to override controllers etc.
