Im stuck uploading multiple photos to my model when adding an extra field to the photo model. In the code i hard code "1" value to the hidden_field, but i will change it eventually. The paperclip gem raises a rollback and won't insert the photos in the post. If i erase the "hidden_field" line it will success. Any ideas on how to add extra field to the upload in the view?
<%= form_for #campaign_point_of_sale, :html => {:multipart => true }, :url => "/pos/#{#point_of_sale.id}/post/#{#campaign.id}", :method => :post do |f| %>
<%= f.hidden_field :id %>
<label>Add photo <br />
<%= f.fields_for :campaign_result_point_of_sale_photos do |builder| %>
<% if builder.object.new_record? %>
<%= builder.hidden_field :is_mount_photo, :value => "1" %>
<%= builder.file_field :photo %>
<% end %>
<% end %>
<%= f.submit(:value => "Save") %>
Got it!
Just needed to delete the whole builder with both hidden_field and file_field, so the server would not try to insert a picture without an image file (just with a hidden_field value)
This can be achivied by surrounding both inputs with a div and deleting it (with jquery) at form submit if the file_field value was empty. Pretty cheap but works!

I have a button that links to the projects updates index action through all_project_updates_path i set in my routes. Here is my button code:
<%= button_tag type: "button", :class => "radius" do %>
<%= link_to 'Project Updates', all_project_updates_path(#project), :style => "color: white" %>
<% end %>
I want this button to only be visible when there are project updates in the database. Otherwise I want this button to dissapear. I tried:
<% if all_project_updates_path(#project) != nil %>
<%= button_tag type: "button", :class => "radius" do %>
<%= link_to 'Project Updates', all_project_updates_path(#project), :style => "color: white" %>
<% end %>
<% end %>
And also
<% if #updates != nil %>
<%= button_tag type: "button", :class => "radius" do %>
<%= link_to 'Project Updates', all_project_updates_path(#project), :style => "color: white" %>
<% end %>
<% end %>
but that doesn't seem to work. Looking for a simple explanation as I am a relative beginner with ruby.
This is the route:
get 'all_project_updates/:id' => 'project_updates#index', as: 'all_project_updates'
This is my projects controller(show action)
def show
#project = Project.find(params[:id])
#comments = Comment.all.where(:project_id => #project.id)
#updates = ProjectUpdate.all.where(:project_id => #project.id)
end
And this is my project updates controller index action:
def index
#projectUpdates = ProjectUpdate.where(:project_id => params[:id])
respond_to do |format|
format.html
end
end
You’re examining a path helper, all_project_updates_path, when you need to be querying a model object. The all_project_updates_path call is a helper to return a path for linking between web pages.
all_project_updates_path(#project) # => /all_project_updates/1
So you’re really asking:
'/all_project_updates/1'.nil? # => false
Because it’s just a string, it won’t be nil.
Instead, you should be examining the project_updates directly. I’m not sure how your models are related, but assuming that a Project has_many :project_updates, try this:
if #project.project_updates.any?
That will return true if a #project has any updates.
Beyond your immediate question, I would recommend considering whether nested resources are a better fit for this usage. You could declare your routes like this:
resources :projects do
resources :project_updates
end
Then you would get project_project_updates_path(#project) and no longer need your custom route that pretty much duplicates that functionality.
Try this:
<% if #updates.any? %>
<%= button_tag ... %>
<% end %>
#updates is an empty collection (ActiveRecord_Relation to be precise) of ProjectUpdate objects if no records were found, it's not nil.
I'm creating a web application with formtastic. I installed the gem and wrote my code like this:
<%= semantic_form_for #index do |form| %>
<%= form.inputs do %>
<%= form.input :name %>
<%= form.input :born_on, :start_year => 1997 %>
<%= form.input :description, :as => :text %>
<%= form.input :female, :as => :radio, :label => "Gender", :collection => [["Male", false], ["Female", true]] %>
<% end %>
<%= form.actions do %>
<%= form.action :submit, :as => :button %>
<% end %>
<% end %>
I want the form to appear on the index page which is why I have #index. For some reason I can't do #index. How would I reference the top line so that it renders a form on the index page? Currently my index page has nothing in it, but it is defined in the controller
form_for helper expects some object that responds to fields You refer inside Your form. Here is an example of using semantic_form_for with plain Ruby object: http://affy.blogspot.com/2010/02/using-formtasic-without-activerecord.html.
Also the object You specify for form doesn't effect which page is being rendered. Are You sure You are not mixing up something? Maybe if You share a bit more of Your controller code we might help You better.
I am lost, I do not know what I'm doing wrong! I have 4 radio buttons and a hidden field (value = "1"). When you click on the second radiobutton, the value of the hidden field changes to 2 and so on. This works fine with a js function.
Different divs will be showed when a different radiobutton is selected. Now, when I'm trying to get the value of the hidden field in my controller it always returns nil.
Here's the code:
view:
(radiobuttons, hiddenfield and one div)
<div>
<%= form_tag patients_path do %>
<%= radio_button_tag 'searchRBN', 'patient', true, :onchange => "checkRadioButton()" %>
<%= label_tag :byPatient_patient, "Patient" %>
<%= radio_button_tag 'searchRBN', 'staff', false, :onchange => "checkRadioButton()" %>
<%= label_tag :byStaff_staff, "Staff" %>
<%= radio_button_tag 'searchRBN', 'ocmw', false, :onchange => "checkRadioButton()" %>
<%= label_tag :byOcmw_ocmw, "OCMW" %>
<%= radio_button_tag 'searchRBN', 'mutuality', false, :onchange => "checkRadioButton()" %>
<%= label_tag :byMutuality_mutuality, "Mutuality" %>
<%= hidden_field_tag :hidden_one, "1" %>
<% end %>
</div>
<div id="searchByPatient">
<%= form_tag patients_path, :method => 'get' do %>
<p>
<%= text_field_tag :search1, params[:search1] %>
<%= submit_tag "Search", :name => nil %>
</p>
<% end %>
</div>
controller:
def index
#staff_all = Staff.all
#ocmw_all = Ocmw.all
#mutuality_all = Mutuality.all
debugger
if params[:hidden_one] == '1'
#patients = Patient.searchByName(params[:search1])
elsif params[:hidden_one] == '2'
#patients = Patient.searchByStaff(params[:search2])
else
#patients = Patient.all
end
end
It's because you have two forms. When you submit the second form it won't send the fields of the first form. If you put everything in one form it will work as expected.
Use only single form:
Also as a workaround use two submit tag in a single form:
differentiate both the action with params[:action]
For Example:
<%= form_for :attachment_metadata, :url=>{:action=>'delete_files'}, :html=>{:onsubmit=> "return confirm('Are you sure, you want to delete selected files?');",:multipart => true} do |f| %>
<table>
..........Some stuff here..........
</table>
<%= submit_tag 'Reprocess', :class =>'button' %>
<%= submit_tag 'Remove', :class =>'button' %>
<% end %>
params[:commit] can differentiate the actions of two submit tags.
#action = params[:commit]
it gives #action value as "Reprocess" if your click the Reprocess button and gives "Remove" value if you click the Remove button,
Then you will get your values.
Good day! Little newbee question:
let's say I want to generate fields of form_for helper of special appearance. Thus to not to repeat complex code to generate many fields of model, I render some partial and pass there parameters. There is a reference to form object amongst them. Question is what pass to render method to call in the partial necessary method of form object? For example I want to generate this time email_field:
<%= form_for #order do |f| %>
<%= render :partial => 'form_field_special', :locals => {:form => f, :type => :email_field, :labelcaption => "SpcName"} %>
<% end %>
and partial itself:
<div class="control-group">
<%= f.label :name, <%= labelcaption %> , :class => "control-label" %>
<div class="controls">
<%= f.type :name %> # ??????
</div>
</div>
thank you guys!
Use ruby power. Object#send method:
<%= form_for #order do |f| %>
<%= render :partial => 'form_field_special', :locals => {..., :field_type => 'email_field'} %>
<% end %>
<%= f.send(field_type, :name) %>
The following method proved as the fastest way to invoke ruby object's function by its name:
m = form.method(name_of_the_method)
m.call(parameters)
I'm trying to prevent a form from being "double posted", when the user either clicks twice or hits submit twice.
I've seen a couple posts on this, but they haven't hit this issue per se. I can't seem to get the below to stop double-posts, and I'm getting the feeling it's related to the remote => true (using ajax to show the content on the page).
Below is my form:
<%= form_for([#posts, #comment], :remote => true) do |f| %>
<%= f.text_field :comment %>
<%= f.submit "Submit", class: "btn btn-large btn-primary", :style => 'display: none;', :disable_with => '' %>
<% end %>
Any recommendations would be great. Thank you!
Use the disable_with option
<%= submit_tag :submit, :id => 'submit_button', :value => "Create!", disable_with: "Creating..." %>
The other answer didn't work for me — I believe it was from the Rails 2 era. According to the docs, the disable_with attribute should be added within a data attribute, like so:
<%= submit_tag "Complete sale", data: { disable_with: "Please wait..." } %>
