I have to pass a value in a form where the user cannot to choose. I have a Register model with some fields. One of them is a value from another Model called Car. I show in the _form view the car plate value but I want to link this value in the form This is the code in _form :
<%= form_for(#reg) do |f| %>
<div class="field">
<p><%= f.label :date %></p><br>
<%= f.date_field :date_reg %>
</div>
<div class="field">
<p><%= f.label :car_id %></p><br>
<% Car.all.each do |car| %>
<%= car.plate %>
<%= f.select(:driver_id,
options_from_collection_for_select(Driver.all, :id,
:name), {:prompt => 'Please Choose'}, :class => "form-
control") %><br>
<% end %>
</div>
<div class="field">
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Thanks all

<%= form_for #bug do |f| %>
<div class="form-group">
<%= f.label :description %>
<%= f.text_field :description %>
</div>
<div class="form-group">

I have this code in my form. I want to know the value user selects for :bugtype, in order to display status accordingly. I am not able to access value of bugtype using instance variable or f.object.bugtype
I have a rails app where user can assign task to another user by creating task action. At the moment I have the f.collection_select, but as the number of users grows it won't be a good solution. I would like to change it into kinda search form. My problem is that I don't see how I can do this. I have other search forms, but those are for show/index action. How can I do this for the create action?
here is my current code:
<%= form_for ([#user, #task]) do |f| %>
<%= render 'layouts/error_messages', object: f.object %>
<div class="field form-group">
<%= f.label :executor_id %>
<%= f.collection_select(:executor_id, User.all, :id, :email, class: "form-control") %>
</div>
<div class="field form-group">
<%= f.label :content %>
<%= f.text_area :content, class: "form-control" %>
</div>
<div class="field form-group">
<%= f.label :deadline %>
<%= f.date_select :deadline, class: "form-control" %>
</div>
<div class="actions">
<%= f.submit "Create Task", class: 'btn btn-primary', "data-sid" => current_user.id, "data-rip" => :executor_id %>
</div>
<% end %>
My submit button won't work because of the first if statement. If I remove the block, the button works. The statement seems to break the view. Why?
<% if params[:action] == "edit" %>
<div class="field">
<%= form_tag :action => "edit" do %>
<%= select_tag :vehicle_id, options_from_collection_for_select(#vehicles, :id, :model, params[:id].to_i), :onchange => "this.form.submit()" %>
<% end -%>
<%= link_to 'Nouvelle voiture', new_vehicle_path %>
</div>
<% end -%>
<div class="field">
<%= f.label "Modèle" %>
<%= f.text_field :model, required: true %>
</div>
<div class="field">
<%= f.label "Immatriculation" %>
<%= f.text_field :license_plate, required: true %>
</div>
<div class="field">
<%= f.label "Complément" %>
<%= f.text_field :complement, required: true%>
</div>
<div class="field">
<%= f.label "Puissance CV" %>
<%= f.number_field :horse_power, required: true %>
</div>
<div class="field">
<%= f.label "Indemnité KM" %>
<%= f.number_field :km_compensation, required: true%>
</div>
<% if params[:action] == "edit" %>
<%= link_to 'Détruire', #vehicle, method: :delete, data: { confirm: 'Êtes-vous sûr ? Les trajets associés seront aussi détruits.' } %>
<h1>Trajets</h1>
<div>
<span>Clients</span>
<span>Kms aller/retour</span>
</div>
<%= f.fields_for :trip_distances do |builder| %>
<div class="field">
<%= builder.text_field :id_contract %>
<%= builder.number_field :length %>
</div>
<% end -%>
<% end -%>
<div class="actions">
<%= f.submit 'Sauvegarder' %>
</div>
When you put if statement you don't have form in which your submit button resides. Without if statement your form is in the view, and you can submit to it.
Found the solution. I didn't need the form_tag:
<%= form_tag :action => "edit" do %>
my view is
<h3> Register New Items </h3>
<div class="row">
<div class="span2 offset4">
<%= nested_form_for #item_category, :url => items_path, :method => :post, :html => { :class => "item_category"} do |f| %>
<div><%= f.label :item_name %>
<%= f.text_field :item_name %></div>
</br>
<div>
<%= f.fields_for :item_companies do |f| %>
<%= f.label :company_name %>
<%= f.text_field :company_name %>
</div>
</br>
<%= f.fields_for :item_weights do |f| %>
<div>
<%= f.label :weight %>
<%= f.text_field :weight %>
</div>
</br>
<div>
<%= f.label :price %>
<%= f.text_field :price %>
</div>
<%end%>
<%end%>
<div><%= f.submit "Submit" %></div>
<% end %>
</div>
and controller
def new
#item_category = ItemCategory.new
item_company = #item_category.item_companies.build
item_company.item_weights.build
end
and when I have applied debugger in create action and I saw value of params[:item_category] and this is generated {"item_name"=>"iname", "item_companies_attributes"=>{"0"=>{"company_name"=>"cname", "item_weights_attributes"=>{"0"=>{"weight"=>"20kg", "price"=>"100"}}}}}
ItemCategory.new(params[:item_category])
generated error
ActiveModel::MassAssignmentSecurity::Error Exception: Can't mass-assign protected attributes: item_companies_attributes.
Where i am wrong and how to save value in three tables using this.
It seems that you forgot to add this piece of code in your ItemCategory model:
attr_accessible :item_companies_attributes
which will allow you to set these attributes.
I have 5 models,
Person
person_car
car (has many tires)
person_car_tire
tire (belongs to car)
so I have this view
_form.html.erb
<%= form_for(#person) do |f| %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
<div>
<% Car.all.each do |c|%>
<div class="field">
<%= f.fields_for(:person_cars) do |ff|%>
Car Name: <%= ff.check_box :car_id %>|<%= c.car_name%>
<% c.tires.each do |b|%>
<div class="field">
<%= ff.fields_for(:person_car_tires) do |fff|%>
Tire: <%#= fff.check_box :tire_id%>|<%= b.tire_name%>
<%end%>
</div>
<%end%>
<%end%>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
And when I save it works perfectly, the problem comes when I want to edit using this form because it duplicates data of each car 4 times in the view. I've been searching and fields for allows extra options so I made:
<%= form_for(#person) do |f| %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
<div>
<% #person.cars.each do |c|%>
<div class="field">
<%= f.fields_for(:person_cars, c) do |ff|%>
Actividad: <%= ff.check_box :car_id %> | <%= c.car.name%>
<% c.person_car_tires.each do |t|%>
<div class="field">
<%= ff.fields_for(:person_car_tires, t) do |fff|%>
Tarea: <%#= fff.check_box :tire_id%>|<%#= t.tire.name%>
<%end%>
</div>
<%end%>
<%end%>
</div>
<%end%>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
and it now works, but only show the cars and tires that I've selected on the new action. not all as I wanted (because if I use the first form it duplicates checkboxes in the view).
How can I use the same form for both actions?
Hope someone can help me.
You can use the same _form partial for both new and edit. You just need to pass local variables set to different values to this form. Basically, whatever differs, abstract it away as a parameter (local variable) to this function-like partial.
