simple-form is simply not looking up i18n translations. I was trying it on the placeholders.
simple_form.en.yml
en:
simple_form:
placeholders:
company:
name: "Company name"
The form:
<%= simple_form_for #company,
url: company_path(#company) do |f| %>
<div class="form-group">
<%= f.text_field :name, class: "form-control" %>
</div>
I've debugged using i18n-debug, and it didn't seem to attempt to look up
en.simple_form.placeholders.company.name
at all. Other non simple-form i18n lookups are triggering just fine.
Did I miss a step to 'turn on' i18n for simple-form? I thought it works right out of the box.
Looks like you are using text_field - a Rails form helper. Simple form supports it but it is not implemented in simple form (i.e. falls back to Rails). Change it to f.input :name and it should work.

I'm trying to build a kind of calculator with rails 5.2.
I need to update results fields while I'm writing my input fields. Everything is working perfect with AJAX if I press enter Key on my keyboard but it doesn't work if I try to automaticly submit the form as soon as a field is modified.
the view input.html.erb
<%= form_with url: achatproprietaire_output_path do |form| %>
<div class="form-group mb-3">
<%= form.label :credits_conso, "Montant des crédits conso", for:"example-helping" %>
<%= form.text_field :credits_conso, id: "example-helping", placeholder: "crédits conso", class: "form-control", id: "crédit_conso" %>
<span class="help-block"><small>en euros par mois</small></span>
</div>
js file calles un application.js
$(document).ready(function(){
$("#crédit_conso").keypress(function(){
//this.form.trigger('submit.rails');
Rails.fire(form, 'submit');
});
});
js.erb file correctly called with enter key
$('#output_col').replaceWith("<%= j render 'output', capacité_emprunt_maximal: #capacité_emprunt_maximal,
montant_mensuel_maximal: #montant_mensuel_maximal,
taux_interet: #taux_interet,
taux_assurance: #taux_assurance %>");
And I have no render or redirect_to in my controller.
I've also tried to put onchange: "Rails.fire(this.form, 'submit')" in the form fields but it submit the form without AJAX.
I tried the ckeditor and it works fine when adding or making a new post but the problem is when I try and edit the post.
it doesn't load properly and it doesnt show anything like the code , or even a spec, it just shows the pre default ckeditor list and it doesn't even show any data coming from the database.
any help would really be great, and info would be awesome.
I have made it into a form and then rendering it so that I can just call the function like so.
This is the _form
<p>
<%= f.label :text %><br>
<%= f.cktext_area :text, :value => 'Default value', :id => 'sometext' %>
</p>
Now this is in my edit
<%= render 'form' %>
I tried adding the raw into it like so
<%= raw render 'form' %>
or even into the _form but it doesn't seem to show properly
after tinkering and trying the usual thing the codes show it.
<p>
<%= f.label :text %><br>
<%= f.text_field :text %>
</p>
when I try it and add this now it shows here , but the ckeditor doesn't show properly.
Just give this:
<p>
<%= f.label :text %><br>
<%= f.cktext_area :text %>
</p>
I hope you are calling this partial inside a form_for.
Update the answer,
Just remove
:value => 'Default value',
I have trouble displaying error message for invalid inputs using Ruby on rails. If anyone can help me with it? Currently new to the area.
I suspect the area is due to :user and #user.
This is my form generated on index.html.erb
<%= form_for :user, url: '/login', html:{id:"form"} do |f| %>
<h2 class="login">Login</h2>
<div class="form">
<input type="name" placeholder="Name" name="user[name]" class="form-input" required /></div>
<% end %>
My ActiveRecord Model:
class User < ActiveRecord::Base
validates :name, :uniqueness => true
has_secure_password
end
I try to use the following error handling, by passing the following code after <%= form_for :user, url: '/login', html:{id:"form"} do |f| %> but it did not work with and showed:
NoMethodError in Users#register
: undefined method `errors' for nil:NilClass
<% if #user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#article.errors.count, "error") %> prohibited this article from being saved:</h2>
<ul>
<% #user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
You should be able to do something like this.
/app/views/shared/_error_messages.html.haml:
- if object.errors.any?
.alert.alert-danger
The form contains #{pluralize(object.errors.count, "error")}.
%ul#error_explanation
- object.errors.full_messages.each do |msg|
%li= msg
Then, wherever you want errors to be shown in your views, something like:
= render 'shared/error_messages', object: f.object
Note object in the method. When you call, you could pass either an object instance from your controller or (in the above case), the object of a form builder.
Here is the users show view where they are supposed to show up. ..
<section>
<div id= "purchases">
<%= render 'shared/micropost_form_purchase' %>
</div>
<div id="sales">
<%= render 'shared/micropost_form_sale' %>
</div>
</section>
<%= #sales %> <%# This is just to see if it outputs anything. It doesn't :( %>
<div id="purchases list">
<ol class="microposts">
<%= render #purchases unless #purchases.nil? %>
</ol>
</div>
<div id="sales list">
<ol class="microposts">
<%= render #sales unless #sales.nil? %>
</ol>
</div>
so the forms (partials) are loading fine, but then when I make a post, in either one, neither the purchases list nor the sales list shows up. I checked the database and they are being created along with an entry in the column indicating kind (either sale or purchase).
Here are the forms:
<%= form_for (#micropost) do |f| %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= hidden_field_tag 'micropost[kind]', "purchase" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
and
<%= form_for (#micropost) do |f| %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= hidden_field_tag 'micropost[kind]', "sale" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
also, here is the show part of the users_controller.rb
def show
#user = User.find(params[:id])
#micropost=Micropost.new
#microposts = #user.microposts.paginate(page: params[:page])
end
and here is the show part of the microposts_controller.rb
def show
#micropost = Micropost.find(params[:id])
#microposts = Micropost.where(:user_id => #user.id)
#purchases= #microposts.collect{ |m| m if m.kind == "purchase"}.compact
#sales = #microposts.collect{ |m| m if m.kind == "sale"}.compact
end
additionally, with the help of this post (http://stackoverflow.com/questions/12505845/ruby-error-wrong-number-of-arguments-0-for-1#12505865) the variables #microposts, #purchases, and #sales are all outputting correctly in the console.
can anyone help me out?
edit: using scopes as suggested by the answer given works in the console (it outputs everything correctly, but they still don't show up in the view. Does this mean it is something wrong with my syntax for the users show page?
edit 2:
Here is the view/microposts/_micropost.html.erb code
<li>
<span class="content"><%= micropost.content %></span>
<span class="timestamp">
Posted <%= time_ago_in_words(micropost.created_at) %> ago.
</span>
<% if current_user?(micropost.user) %>
<%= link_to "delete", micropost, method: :delete,
confirm: "You sure?",
title: micropost.content %>
<% end %>
</li>
I'm making some assumptions without seeing more of your code, but it looks like you could
write what you've shown a little differently. I'm assuming your databases are migrating
and have the required columns, e.g., Micropost#kind, Micropost#user_id, etc.
You can use scopes to refine a collection of microposts more expressively. It might be helpful to read
up about ActiveRecord scopes: http://guides.rubyonrails.org/active_record_querying.html#scopes.
class Micropost < ActiveRecord::Base
belongs_to :user
scope :purchases, where(:kind => "purchase")
scope :sales, where(:kind => "sale")
# your code
end
I'm also assuming your user has many microposts:
class User < ActiveRecord::Base
has_many :microposts
# your code
end
For your forms, I'd suggest attaching your hidden field to the form object (f.hidden_field) so
you don't have to specify the name as 'micropost[kind]'.
<%= form_for(#micropost) do |f| %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= f.hidden_field :kind, :value => "sale" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
In MicropostsController#show, you can use your new scopes:
def show
#micropost = Micropost.find(params[:id])
#microposts = #user.microposts
#purchases = #microposts.purchases
#sales = #microposts.sales
end
You should also confirm that your MicropostsController#create action is actually adding
the microposts to the user sending the form (I'm assuming a current user method).
def create
#micropost = current_user.microposts.create(params[:micropost])
# yada
end
You can also confirm expected results on rails console after creating purchases or sales micropost with:
Micropost.purchases
Micropost.sales
Again, I could be missing something without seeing more of the code base.
Check Micropost.count, #purchases.count, #sales.count (by printing them in the controller, or some part of the view) to see if the records actually exist.
Also, if you want to render collections likes #sales and #purchases, you need to make sure that the model partial exists (_micropost.html.erb in your case). That is probably where you need to look for the view errors. For all you know, that file could be empty, thus no errors will show up at all.
The problem might also lie in your microposts#create (or whichever action that you are saving the micropost in), the micropost should be associated with the current_user:
#micropost = current_user.microposts.build(params[:micropost])
Taking this and your previous question into account, I suggest you go through the original code for the RoR tutorial again (and verify that all tests are passing) before taking it apart. You can always add new tests to it for your experiments and they will help in figuring out where you went wrong.
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..." } %>
