I have legacy rails 3 app, where I need to modify a page to use tinymce to edit a text_area.
There are existing pages in this app that already use tinymce.
For reasons I cannot go into here, I cannot use any of the tinymce plugins that are available.
Now my problem is as follows.
I have a model called Sections, that has two attributes, section_name and html.
I want to be able to edit the html using tinymce.
My view has a form which is as follows
<%= form_for #section , :url => update_section_path , :method => :put do |f| %>
<%= f.hidden_field :id %>
<%= f.label :section_name , "Section Name" %>
<%= f.text_field :section_name %> <br />
<%= f.label :html, "Html" %>
<%= f.text_area :html %>
<%= f.submit "Update" %>
<% end %>
The form appears as expected.
The TinyMCE editor also appears on the page with the original html.
The problem is that when I click on the Update button, the put query sent to my server, does not contain the new modified content of the Html text_area. It sends back the original text that was in that text_area.
Could anyone help me understand why.
Thanks in advance

I found an issue in my html which was causing this. Once I fixed that issue it worked fine

I have a Rails app that is running fine on Rails 3.x and ActiveAdmin 0.6.6. However I want to upgrade it to Rails 5 and ActiveAdmin 1.x. I started the upgrade process first upgrading from 3.x to 4.x and then to 5x, and with ActiveAdmin I tested with 1.0.0 and now I'm using the master from Github.
Everything worked fine with the App in both Rails versions and ActiveAdmin but the ActiveAdmin forms that are in a partial.
The problem is the following:
I have a file app/admin/menu.rb whose has a partial views/admin/menus/_form.html.erb.
The partial contains the form of the Menu.
This is the contents of the partial (views/admin/menus/_form.html.erb):
<%= semantic_form_for [:admin, #menu], builder: ActiveAdmin::FormBuilder do |f| %>
<% f.inputs 'Campos Menu' do %>
<% f.input :project if current_admin_user.admin? %>
<% f.input :title %>
<% f.input :title_en %>
<% f.input :item %>
<% f.input :icon, as: :file %>
<% end %>
<% f.inputs 'Submenus' do %>
<% f.has_many :submenus, heading: '' do |fa| %>
<% fa.input :title, as: :string %>
<% fa.input :title_en, as: :string %>
<% fa.input :kind, as: :select, collection: Submenu.kind_collection %>
<% fa.input :items_as, as: :select, collection: Submenu.items_as_collection %>
<% end %>
<% end %>
<% f.actions do %>
<% f.action :submit %>
<% end %>
<% end %>
The render result of this file is only the 'actions' buttons, in this case the 'submit' button. The interesting thing is that if I remove the <% f.actions do %>... from the partial then the <% f.inputs 'Submenus' do %> gets rendered and the same if I remove the later. In other others is being rendered on the last block that contains an end.
The same behaviour is being observed on Rails 4.x and 5.x (except Rails 5.1.x which I didn't tested).
If I move the form from the partial to the app/admin/menu.rb it gets rendered properly. This could be a solution for me however I have others forms that make use of JQuery for fields manipulation and other stuff on the front end.
As I said before, all these forms partials were working properly on Rails 3.x and ActiveAdmin 0.6.6.
Anyone knows what's the problem?
DISCLAIMER: I'm not a Rails or ActiveAdmin expert, so bear with me if is a silly mistake related to this issue.
Yes, it's activeadmin#3486 I'm glad you figured out the workaround. I'm curious if this Arbre branch fixes it for you. Glad to see people still upgrading, I'll do what I can to help.
The solution that I found was to put a = for the <% f.input(s) %> on the partial. Having something like this <%= f.inputs ... %> instead of this <% f.inputs ... %> solves the problem.
I am trying generate a code that tracks for documents that revolve within the organisation. I have done other codes for adding employees, adding document types and logging in now I am struggling on creating a document form and search from the document that I have created. This code is for searching:
controller#show
def show
#generate_documents = GenerateDocument.where('Reciever LIKE?',"%#{params[:search]}%")
# #generate_documents = GenerateDocument.all
end
views/show
<%= form_tag generate_document_path, :method => :get do %>
<p>
<%= text_field_tag :search, params[:search] %>
<%= submit_tag "Search" %>
</p>
<% end %>
<!-- end of seaerch form -->
<!-- loading data from database and displaying then in a list format BEGIN -->
<ul>
<% #generate_documents.each do |generate_document| %>
<li>
<%= link_to generate_document.Reciever, edit_generate_document_path(generate_document) %>
</li>
<% end %>`enter code here`
</ul>
<!--
END LISTING -->
<%= link_to 'New Generate Document', new_generate_document_path %>
Even Iam new to rails, but i can help you with basics that you need to pass the parameters from the view to the controller, therefore you can use:
:url => {:controller => "name_of_your_controller", :action => "action_to_be_perforemed", :id => "whatever id you want"}
or else you can also pass the object within the url like we do while edit request
<%= link_to "Edit", edit_post_path(#edit)%>
which will give the :id of the particular post.
Hope this may help you.
I am developing a web app where people can post new questions. Each question contains many sub-questions, and each sub-question can have many images. To post new questions, I use a Rails plug-in called 'nested-form', and to add pictures I use Paperclip.
Here is my question. When I add new questions, everything works fine. But when I edit the question, the fields for the pictures are still there but the picture directories in the fields are gone. If I submit the form with the blank fields, all the pictures would be gone. Therefore, I have to upload all the pictures again when I edit a question, even if I don't want to do any change to the pictures.
Here is my code:
new_question.html.erb:
<%= nested_form_for #question, :url => {:action => 'create_question'} do |f| %>
<%= f.label :name # some fields for #question %>
<%= f.text_area :name %>
<%= f.fields_for :subquestions do |builder| %>
<%= render 'subquestion_fields', :f => builder %>
<%= builder.link_to_remove 'Remove Sub-question' %>
_subquestion_fields.html.erb:
<%= f.hidden_field :_destroy %><br>
<%= f.link_to_add 'Add an image', :qimages %><br>
<%= f.fields_for :qimages, :html => { :multipart => true } do |builder| %>
<%= render 'qimage_fields', :f => builder %>
<%= builder.link_to_remove 'Remove this image' %><br>
<% end %>
_qimage_fields.html.erb:
<%= f.file_field :image %>
edit_question.html.erb uses the same partials above, but the picture that are already added to the question are not displayed(leaving blank 'qimage' fields). Is there a way to display all the images when editing the question?
Thank you!
Sorry. I just found out that there is a solution on Ryanb's Nested Form page. It is possible to track the event that generates new fields by listening to the nested:fieldAdded event, and the generated elements can be found by via event.field.
I have a text_area in a partial in a complex form that is called like so
<%= f.fields_for :notes do |notes_form| %>
<%= render :partial => 'note', :locals => {:f => notes_form, :operation => f, :count => operation.notes.count} %>
<% end %>
<p><%= add_child_link "Add note", :operation_notes %></p>
and the partial looks like this
<% count ||= 2 %>
<div class='fields'>
<%= f.text_area :note_text, :rows => "4", :class => "notes" %>
<%= remove_child_link "x", f, count %>
</div>
There can be many notes on the form hence the add and remove child links.
The issue I'm having is that if I add a note with the text 'abcd', when I bring up the edit form I get '<p>abcd</p>'. If there are line breaks in the note it adds <br /> tags. The text_area form helper seems to be using the simple_format helper but I have no idea why. Can anyone help as this is very undesirable behaviour?
Ah solved,
Earlier on the same page I was displaying the note and using simple_format to format it with
<%= simple_format note.note_text %>
It seems that simple_format is somewhat destructive as after this, a call to note.note_text always returns the formatted text. If I change the above to
<%= simple_format note.note_text.dup %>
then the note_text attribute is not altered and I get the appropriate results.
I will have to look more closely at simple_format but this really strikes me as undesirable behaviour.
EDIT
It looks like this has been corrected in Rails 3.1
I would suspect that you have something in your Note model that is processing the text. Check for callbacks in this model.
I am using Rails 3.0, Ruby 1.9.2 and the Plataformatec simple_form gem. This code works with a form_for but not simple_form_for:
<%= simple_form_for(#provider) do |f| %>
<% Car.all.each do |c| %>
<div>
<%= check_box_tag :car_ids, c.id, #store.cars.include?(c), :name => 'store[car_ids][]' %>
$<%= c.cost %> | <%= c.description %>
</div>
<% end %>
<div class="actions">
<%= f.submit "New" %>
</div>
<% end %>
How do I get it to work with simple_form_for?
Thanks in advance!
You can't use simple_form right the same way as form_for.
For example ther is no any check_box_tag method in simple_form gem. There is ONLY inuput fields that you can specify with :as option. So your check_box_tag will be converted to
f.input car_ids, ..., :as => :check_box

The problem was in the controller code.
In the "new" controller action I can't simply perform:
#provider = Provider.new(params[:provider])
as one would normally.
Instead I have to process each parameter separately:
#provider.location = params[:provider][:location]
etc...
For the Car check boxes, I add each car_id from the car_ids parameter to the "has_many" cars model association one at a time:
car_ids = params[:provider][:car_ids]
car_ids.each do |cid|
#provider.cars << Car.find(cid)
end
Then I can call:
#provider.save!
And it saves correctly (my initial problem was that it wasn't saving the selected Cars).
For some reason, I was able to figure this out only after posting the question here. Funny how that works.
Thanks all for your replies!
