I've got model with many associations.
User :has_many => :posts, :videos, :images etc
I've got helper method, which receives one of this association
draw_chart user.videos
def draw_chart(assoc)
assoc.each do |a|
link_to "update", [a.user, a], :method => :put, :remote => true, :confirm => 'orrly?'
end
end
Problem here is to send extra parameters to update action.
For example I want to get this url: /users/1/videos/2?status=done but I am confused how to realize this while I am using [a.user, a] instead of user_videos_path(video, :status => 'done'). But I can't use last, because it can be either videos, or images or anything else
I wont go using eval, how about this
<%= link_to('update', self.send("user_#{a.class.name.pluralize}_path", a, , :status => 'done'), :method => :put, :remote => true, :confirm => 'orrly?') %>
Only solution I can think up is this strange one:
link_to "update", eval("user_#{a.class.name.tableize}_path(#{a.school.id}, #{a.id}, :status => 'done')"), :method => :put, :remote => true, :confirm => 'orrly?'
but this looks messy

I am redirecting a user to a custom controller action like this:
<%= link_to url_for(:controller => :jobs, :action => :saved) do %>Saved Jobs<% end %>
it works fine, now i want to pass some value to action "saved".
Do you have any idea how to do this?
Try This
If you want to send the form directly by reloading the page as you are doing,
<%= link_to url_for(:controller => :jobs, :action => :saved, method: :post, :email => "value") do %>Saved Jobs<% end %>
If you want to send it through ajax call from background, add :remote => true to the form,
<%= link_to url_for(:controller => :jobs, :action => :saved, method: :post, :email => "value", :remote => true) do %>Saved Jobs<% end %>
Then in controller
#email = params[:email]
i'm struggling to understand why this is happen with destroy method since everything on controller and routes is ok!
if someone passed through this way please could give me a hint?
Routes
resources :users, :as => "" do
resources :sections, :only => [:new, :create, :destroy, :index]
end
Controller
def destroy
#section = Section.find(params[:id])
#section.destroy
redirect_to sections_url
flash[:notice] = "Section deleted"
end
View
<%= render :partial => "section", :collection => #sections %>
Partial
<%= link_to section.name, section_path(current_user, section) %>
<%= button_to 'Remove', current_user, section, :data => { :confirm => 'Confirm?' }, :class=> "buttom", method: :delete %>
That error means that some function takes 1 to 3 arguments, but you gave to it 4 arguments.
Please see the row number in the error and look up the function, then open documentation and look up how to use that function. Often functions works differently as instance methods and class methods.
The problem seems to be this method call:
button_to 'Remove', current_user, section, :data => { :confirm => 'Confirm?' }, :class=> "buttom", method: :delete
The pair current_user and section has to been passed as an array:
button_to 'Remove', [current_user, section], confirm: 'Confirm?', class: "buttom", method: :delete
Your button_to helper arguments are wrong.
Try this:
<%= button_to 'Remove', {:action => :destroy, :user => current_user, :id => section}, {:data => { :confirm => 'Confirm?' }, :class=> "buttom", method: :delete} %>
codeit, Stefan did what you guys said but did not work, so i tried the path instead and worked!
<%= button_to 'Remove', section_path(current_user, section), :data => { :confirm => 'Confirm?' }, :class=> "button", method: :delete %>
So I was wondering how to work with the link_to method and ajax in Rails 3, when redering different partials.
Example:
Let say I have two link in show.html.erb and every link have a partial to render.
<li><%= link_to "Group1", user_path(#user), { :action => 'group1' , :method => :get, :remote => true} %></li>
<li><%= link_to "Group2", user_path(#user), { :action => 'group2' , :method => :get, :remote => true} %></li>
And we are going to render the partials in this div:
<div id="profile-data">
...render here...
</div>
In the UsersController we have our call methods for each partial:
def group1
respond_to do |format|
format.js
end
end
def group2
respond_to do |format|
format.js
end
end
And of course we have our js files in the view user folder:
group1.js.erb
$("#profile-data").html("<%= escape_javascript(render(:partial => 'group1')) %>");
group2.js.erb
$("#profile-data").html("<%= escape_javascript(render(:partial => 'group2')) %>");
So my question is:
is this the right way to render different partials with ajax? Are I missing something? Do have to route them some way?
This code dosent work right now and I dont know why, any help would be appreciated.
You need to explicitly state that you want to make a javascript request in your link_to.
This can be done be setting the format in the options hash to js with: :format => :js.
So in your case it should look like this:
<li><%= link_to "Group1", user_path(#user), { :action => 'group1' , :method => :get, :remote => true, :format => :js} %></li>
<li><%= link_to "Group2", user_path(#user), { :action => 'group2' , :method => :get, :remote => true, :format => :js} %></li>
The link_to should be somewhat like
<%= link_to "Group1", {group1_users_path, :format => :js} , :method => :get, :remote => true %>
or
<%= link_to "Group1", {:controller=>:users,:action=>:group1, :format => :js} , :method => :get, :remote => true %>
or if it is a member route and needs user_id
<%= link_to "Group1", {group1_users_path(#user) :format => :js} , :method => :get, :remote => true %>
The second param for link_to is the url options so only the url related option go in it, others should be out of the hash or else they will be just passed as params.
Check out more details at rails cocs they have some neat docs and examples
http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to
You need to have group1 and group2 in routes file
it should be like
resourses :users do
collection do
get "group1"
get "group2"
end
end
this will add helpers group1_user_path and group2_user_path
I recemmond you to go through rails docs thoroughly
http://guides.rubyonrails.org/routing.html#adding-more-restful-actions
I have a link_to like this:
<%= link_to "Nuevo Contrato", {:controller => "hotels", :action => "edit", :id => #hotel_id, :selected_tab => "4"}, :class => "new_link" %>
There's a way to send those parameters not using the query string for it? (using post instead of a get) ??
Thank you!
I already tried:
<%= link_to "Nuevo Contrato", {:controller => "hotels", :action => "edit", :id => #hotel_id, :selected_tab => "4"}, {:method => :post,:class => "new_link"} %>
And it keeps doing the same thing...!
Add a supported HTTP verb in the method option.
<%= link_to "link", {:method => :post ...} %>
I think you can just add :method => :post to the options of link_to.
Here are the docs (for Rails 3, but I think this still holds true for Rails 2 also) http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to
EDIT FOR UPDATED QUESTION
:method => :post belongs in the HTML options, not the URL options. This is not very obvious from the documentation.
<%= link_to "Nuevo Contrato", {:controller => "hotels", :action => "edit", :id => #hotel_id, :selected_tab => "4"}, {:method => :post, :class => "new_link"} %>
This seems incredibly similar to a question I had answered just a few days ago, but the solution then isn't working now.
I'm building a rails app, and I am trying to have a button_to trigger a destroy in a different controller.
the code I have for the button is
<%= button_to "delete", :controller => :meals,
:action => 'destroy',
:recipe_id => recipe.id,
:method => :post >
when I click the delete button, i get a
'no matches for meals/3' which is the current meal_id.
the destroy in the meals controller looks like this
def destroy
#meal = Meal.where("current_user.id => ? AND recipe_id => ?", current_user.id, params[:recipe_id]).first
#meal.destroy
respond_to do |format|
format.html { redirect_to :controller => "user" , :action => "show" }
format.xml { head :ok }
end
end
it appears as though the button_to is completely ignoring the :action and requesting show which does not exist and shouldn't exist.
And how you part of routes.rb for that one looks like?
Because if you use map.resources then destroy has same path as show but :method => :delete(which is virtual verb implemented by form and _method=delete param).
Try this:
<%= button_to "delete", {:controller => :meals,
:action => 'destroy', :id => recipe.id }, :method => :delete %>
or if recipe is instance of Meal class then
<%= button_to "delete", #recipe, :method => :delete %>
Mind the curly brackets.
I know it is way too late for an answer but hope it may help somebody(using Rails 4).
<%= button_to "delete", meal_path(:id => recipe.id), :method => :delete %>
