I have a nested model. How to check attribute value of object(hotel) of neted model in edit form? I can't figure out how to write if/else statement in _hotels_fields.html.erb
edit.html.erb
<% provide(:title, "Edit trip") %>
<h1>Edit trip</h1>
<%= form_for(#trip) do |f| %>
<%= render 'fields_edit', f: f %>
<%= f.submit "Save changes" %>
<% end %>
_fields_edit.html.erb
<p>
<%= f.label :image %>
<%= f.file_field :image %>
</p>
<p>
<%= f.label :content %>
<%= f.text_area :content %>
</p>
<p>Hotel</p>
<%= f.fields_for :hotels do |builder| %>
<%= render 'hotels_fields', f: builder %>
<% end %>
_hotels_fields.html.erb
<% if #trip.hotels.name == "hotel" %>
<p>Render any text</p>
<% end %>
<fieldset>
<p>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :description %>
<%= f.text_field :description %>
</p>
</fieldset>
In the context of _hotels_fields.erb.html one specific hotels (why plural here if you have only one?) is represented by f.object. Therefore this should work:
<% if f.object.name == 'hotel' %>
...
<% else %>
...
<% end %>

I have the following code in my
new.html.erb
<%= form_tag puppies_path do %>
<% #kennel.each do |puppy| %>
<%= fields_for 'puppies[]', puppy do |p| %>
<div class="field">
<%= p.label :name %><br>
<%= p.text_field :name %>
</div>
<div class="field">
<%= p.label :breed %><br>
<%= p.text_field :breed %>
</div>
<% end %>
<% end %>
<div class="actions">
<%= submit_tag %>
</div>
<% end %>
And puppies[] array variable, which is supposed to post array of objects to controller is posting only single object. Please help to post an array to controller. Thanks in advance!
The usual setup for fields_for is something like this.
<% #kennel.each do |kennel| %>
<%= fields_for :puppies, #kennel.puppies do |p| %>
Yes, I have just found an answer...
In new.html.erb file
<%= form_tag puppies_path do %>
<% 2.times do %>
<%= render 'puppies_group_form' %><br>
<% end %>
<%= submit_tag "Submit" %>
<% end %>
In _puppies_group_form
Name <%= text_field_tag "puppies[][name]" %>
Breed <%= text_field_tag "puppies[][breed]" %>
How can I rewrite the code in duels/_form so I can put the code from dueler_fields directly in there?
duels/_form
<%= simple_form_for(#duel) do |f| %>
<%= f.text_field :consequence %>
<%= f.text_field :reward %>
<%= f.fields_for :duelers do |dueler| %>
<%= render 'dueler_fields', :f => dueler %>
<% end %>
<%= link_to_add_association f, :duelers do %>
<span class="glyphicon glyphicon-plus"></span> Dueler
<% end %>
<% end %>
_dueler_fields
# I want to place these two lines of code in the _form
<%= f.number_field :user_id, placeholder: "Enter User ID" %>
<%= f.number_field :challenge_id, placeholder: "Enter Challenge ID" %>
duels_controller
def new
#duel = Duel.new
respond_with(#duel)
end
duels has_many duelers.
change f to dueler and you should be good to go. or:
<%= simple_form_for(#duel) do |f| %>
<%= f.text_field :consequence %>
<%= f.text_field :reward %>
<%= f.fields_for :duelers do |dueler_form| %>
<%= dueler_form.number_field :user_id, placeholder: "Enter User ID" %>
<%= dueler_form.number_field :challenge_id, placeholder: "Enter Challenge ID" %>
<% end %>
<% end %>
I have model Project and in model have field documents(files). I am using gem dragonfly. When editing a project, how to make the list of current files? At this time on the edit page the list of files fields show: "The file is not selected". I do next:
projects_controller:
def edit
end
def update
if #project.update(project_params)
redirect_to #project
else
render :edit
end
end
private
def set_project
#project = Project.find(params[:id])
end
def set_payment_types
#payment_types = PaymentOption.all
end
def project_params
params.require(:project).permit(:title, :description, :price, :location,
:anonymity, :price_category, :category_id, :skill_list, documents_attributes: [:attachment], payment_option_ids: [])
end
edit.html.erb:
<%= form_for #project do |f| %>
<p>
<%= f.label 'Name' %>
<%= f.text_field :title %>
</p>
<P>
<%= f.label 'Budget' %>
<%= f.text_field :price %>
für
<%= f.select :price_category, Project::PRICE_CATEGORIES %>
</P>
<p>
<%= f.label 'Description' %>
<%= f.text_area :description %>
</p>
<p>
<%= f.label 'Category' %>
<%= f.collection_select :category_id, Category.all, :id, :name %>
</p>
<p>
<%= f.label 'Skills Freelancer (15 pieces) *' %>
<%= f.text_field :skill_list %>
</p>
<p>
<%= f.label 'Location' %>
<%= f.text_field :location %>
</p>
<ul>
<% #payment_types.each do |type| %>
<li><%= check_box_tag 'project[payment_option_ids][]', type.id %>
<%= type.name %>
</li>
<% end %>
</ul>
<p>
<b>Anonymity order</b>
</p>
Setup allows for players to remain anonymous. Note that this may reduce the number of responses.
<p>
<%= f.label 'Place Order anonymously' %>
<%= f.check_box :anonymity %>
</p>
<p>
<%= f.fields_for :documents do |d| %>
<%= render 'document_fields', f: d %>
<% end %>
<div class="links">
<%= link_to_add_association 'add file', f, :documents %>
</div>
</p>
<P>
<%= f.submit 'Edit' %>
</P>
<% end %>
_document_fields.html.erb:
<div class="nested-fields">
<%= f.label :attachment %>
<%= f.file_field :attachment %>
<%= link_to_remove_association "remove file", f %>
</div>
document.rb
class Document < ApplicationRecord
belongs_to :project
dragonfly_accessor :attachment
end
On the edit page the list of files fields show: "The file is not selected", but must be specified current files.
file_field is for uploading new files only, not for displaying what is already in the database. For displaying a list of uploaded files, you should just display the name of the file and/or an image tag with the thumbnail and provide a destroy link.
You can also provide a link to create a new attachment.
edit.html.erb
<div>
<ul>
<%= #project.documents.each do |document| %>
<li>
<%= document.attachment.name %>
<%= link_to "Delete", document_path(document), method: :delete, data: { confirm: 'Are you sure you want to delete this?' } %>
</li>
<% end %>
</ul>
<div class="links">
<%= link_to_add_association 'add file', f, :documents %>
</div>
</div>
I am trying to make the title increment by number in the form below as the user adds a level (a new form). For example when the user clicks add level it should say "Level 2" and if they add another one it says "Level 3"
Here is the second partial in which the title I would like to increment
<fieldset class="levelCreator">
<%= f.label :title, "Level"%> <br /><%# This is what I would like to increment %>
<%= f.text_field :title %><br />
<%= f.hidden_field :_destroy %>
<%= link_to "remove", '#', class: "btn btn-danger btn-mini remove_fields" %>
<%= f.fields_for :steps do |builder| %>
<%= render 'step_fields', f: builder %>
<% end %>
<%= link_to_add_fields "add step", f, :steps %>
here is the first partial in which the add level button exists
<%= form_for(#course) do |f| %>
<%= render 'shared/error_messages_courses' %>
<div class="courseCreator">
<%= f.label :title %>
<%= f.text_field :title %>
<%= f.label :description %>
<%= f.text_field :description %>
<%= f.label :typeof %>
<%= f.text_field :typeof %>
</div>
<%= f.fields_for :levels do |builder| %>
<%= render 'level_fields', f: builder %>
<% end %>
<%= link_to_add_fields "add level", f, :levels %>
<%= f.submit "Save", class: "btn btn-large btn-primary save" %>
<% end %>
</div>
</div>
It may not be very elegant, but a counter in the parent view should do it:
view:
<% index = 1 %>
<%= f.fields_for :levels do |builder| %>
<%= render 'level_fields', {f: builder, index: index} %>
<% index = index + 1 %>
<% end %>
partial:
<%= f.label :title, "Level #{index}"%>
I currently have a nested model User has_many Sales_Orders has_many Items.
I can create the Sales_Order with nested Items properly but when I try to 'edit' the Sales_Order, the Sales_Order information is visible but the Items are not shown. Any idea why these wouldn't show?
[sales_orders_controller.rb]
...
def edit
#sales_order = SalesOrder.find(params[:id])
end
[edit.html.erb]
<% provide(:title, "Edit SO") %>
<h1>Edit Sales Order</h1>
<div class="row">
<div class="span6 offset3">
<%= form_for(#sales_order) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="span3">
<%= f.label :so, "SO#:" %>
<%= f.text_field :so %>
<%= f.label :customer, "Customer:" %>
<%= f.text_field :customer %>
<%= f.label :enter_date, "Date Entered:" %>
<%= f.text_field :enter_date, value: date_formatter(#sales_order.enter_date) %>
<%= f.label :request_date, "Request Date:"%>
<%= f.text_field :request_date, value: date_formatter(#sales_order.request_date) %>
<%= f.label :comments, "CS Comments:" %>
<%= f.text_area :comments %>
</div>
<div class="span3">
<% f.fields_for #sales_order.items do |builder| %>
<%= render 'item_fields', f: builder %>
<% end %>
</div>
<%= f.submit "Save changes", class: "btn btn-large btn-primary" %>
<% end %>
</div>
</div>
[_item_fields.erb]
<fieldset>
<%= f.label :item_code, "Item Code:" %>
<%= f.text_field :item_code %>
<%= f.label :qty_in_kg, "Qty (kg):" %>
<%= f.text_field :qty_in_kg %>
<%= f.label :qc_comments, "Comments:" %>
<%= f.text_field :qc_comments %>
<%= link_to "remove", '#', class: "remove_fields" %>
</fieldset>
<% f.fields_for #sales_order.items do |builder| %>
should be
<%= f.fields_for #sales_order.items do |builder| %>
Without the = you're building the output in the loop but never rendering/printing the return value (the generated HTML output).
Use <%= f.fields_for #sales_order.items do |builder| %>
Notice the = sign. This implies, "evaluate and embed"
