In my project, the gems that I've used are: rails admin, cancancan and devise.When I do the bundle install, lots of views will be added. I added "can :crud, [xxxx, xxxxx]" to have a CRUD in my ability model.
Question: How do I check the current path in my view? because I want to disable some field. Example: I am in the new path method and have 3 fields for that(then I clicked the submit/create, now it will the added data). I clicked the edit button,then there's one field will be disabled.
Note: The both form of new path and edit path is in the same file(activities_types/_form.html.erb).
View
_Form.html.erb
<% if current_page?(new_activity_type_path) %>
<div class="field">
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<% else %>
<div class="field">
<%= f.label :"name" %>
<%= f.text_field :name, disabled: true %>
</div>
<% end %>
<div class="field">
<%= f.label :description %>
<%= f.text_field :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
if you want to diffenetiate between edit and new actions in view then
<% if params[:action] == "new" %>
...
<% elsif params[:action] == "edit" %>
...
<% end %>
OR
<div class="field">
<%= f.label :name %>
<% if params[:action] == "new" %>
<%= f.text_field :name %>
<% else %>
<%= f.text_field :name, disabled: true %>
<% end %>
</div>
<div class="field">
<%= f.label :description %>
<%= f.text_field :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
I would set up an instance variable in your new and edit methods in your controller, following that up by checking the value in your form.
example:
def new
#whereAmI = "new"
end
def edit
#whereAmI = "edit"
end
In the view:
<% if #whereAmI == "edit" %>
<%= f.text_field :name, disabled: true %>
<% elsif #whereAmI == "new" %>
<%= f.text_field :name %>
<% end %>
You can check the action like this:
if params[:action] == "new"
# doing something
elsif params[:action] == "edit"
# doing something
end

I generated a scaffold for a portfolio via the Rails command, rails g portfolio titre:string, thumbnail:string lien:string description:text. I also added FriendlyId to get a better URL, and that's about all. Here is the 'update' action.
def update
if #portfolio.update(portfolio_params)
redirect_to #portfolio, notice: 'Portfolio mis à jour.'
else
render :edit
end
end
However, when trying to update a project in my portfolio, the submit button tries to get to 'portfolio#update' via patch, but puts a '.' instead of a '/' which gives me No route matches [PATCH] "/portfolios.test-1"
For the route, I only have resources :portfolios
edit : added the form
<%= form_for #portfolio, url: portfolios_path(#portfolio) do |f| %>
<% if portfolio.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(portfolio.errors.count, "error") %> prohibited this portfolio from being saved:</h2>
<ul>
<% portfolio.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :titre %>
<%= f.text_field :titre %>
</div>
<div class="field">
<%= f.label :categorie %>
<%= f.text_field :categorie %>
</div>
<div class="field">
<%= f.label :description %>
<%= f.text_area :description %>
</div>
<div class="field">
<%= f.label :thumbnail %>
<%= f.file_field :thumbnail %>
</div>
<div class="field">
<%= f.label :lien %>
<%= f.text_field :lien %>
</div>
<div class="actions">
<%= f.submit 'Enregistrer' %>
</div>
<% end %>
I didn't have any other possibilities that doing #portfolio, url: portfolios_path(#portfolio), otherwise Rails considered that '#portfolio' was nil
edit 2 : added the private 'set_portfolio' params
private
# Use callbacks to share common setup or constraints between actions.
def set_portfolio
#portfolio = Portfolio.friendly.find(params[:id])
end
What's wrong with my app ?
portfolios_path is the collection path.
change it portfolio_path should fix it.
<%= form_for #portfolio, url: portfolio_path(#portfolio) do |f| %>
I guess you are going to use this form for creating new portfolio as well, so change it to <%= form_for(#portfolio) %> should fix it and will also work for both cases. form_for will submit to correct path.
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]" %>
So I have Users and Interests and they are associated with a has_and_belongs_to_many relation through an interests_users table. What I want to do is to let users select 5 interests when they create their account through checkboxes, but I don't now how to submit the same param 5 times in the same form and I am currently submiting it with checkbox, but Interest is not a boolean. The code right now is like this:
<div class = "field">
<%= f.label :interests %><br>
<% all_interests = Interest.all.map{ |f| [f.name, f.id] } %>
<% all_interests.each do |interest| %>
<p> <%= interest[0] %> <%= f.check_box :interests %> <p>
<% end %>
</div>
In view use the flowing
<% for interest in Interest.all %>
<%= check_box_tag "user[interest_ids][]", interest.id, #user.interests.include?(interest) %>
<%= interest.name %>
<% end %>
In controller accept params as following
params.require(:user).permit( { interest_ids:[] })
You should try this code :
<div class = "field">
<%= f.label :interests %><br>
<% Interest.all.each do |interest| %>
<p> <%= interest.name %> <%= f.check_box :interests, { :multiple => true }, interest.id, nil %> </p>
<% end %>
</div>
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 a form that I copied over from new.html.erb and put it in edit.html.erb. I essentially want the same form, but if there are values already in the database for the form fields I want them to be pulled into the form for editing. I currently have something like this:
<%= form_for #user do |f| %>
<% if #user.errors.any? %>
<div class="error_messages">
<h2>Form is invalid</h2>
<ul>
<% for message in #user.errors.full_messages %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :email %>
<%= f.text_field :email %>
</div>
<div class="field">
<%= f.label :password %>
<%= f.password_field :password %>
</div>
<div class="field">
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation %>
</div>
.
.
.
.
<div class="actions"><%= f.submit %></div>
<% end %>
How can I pull from the the database to fill in the fields with appropriate values?
This will happen automatically if you set #user in the 'edit' action of your controller - something like
def edit
#user = User.find(params[:id])
end
you might also think about including the form as a partial rather than repeating it to DRY up your code - this link gives the general idea
