I'm getting this error undefined local variable or methodtoggle_follow_path'` in the view folder .I probably got something wrong with the method or the use off form_tag + toggle_follow_path any help would be welcome thank you . by the way the goal of the toggle follow is to follow or un follow some one.
in the route file
match '/:username/toggle_follow', to: 'home#toggle_follow'
home controller
def toggle_follow
#user = User.find_by_username(params[:username])
if current_user.is_friend? #user
flash[:notice] = "You are no longer following ##{#user.username}"
current_user.remove_friend(#user)
else
flash[:notice] = "You are now following ##{#user.username}"
current_user.add_friend(#user)
end
redirect_to user_flits_path(#user)
end
view
<h1><%= image_tag #user.gravatar_url, :align => "top" %> <%= #user.username %></h1>
<%= form_tag toggle_follow_path, :method => :post do %>
<% if current_user.is_friend? #user %>
<%=h submit_tag "Following" , :class => "button" %>
<% else %>
<%=h submit_tag "Follow" , :class => "button" %>
<% end %>
<% end %>
<%=h render :partial => "flits_list", :locals => {:flits => #flits }%>
Use :as option for match to specify the desired helper's name:
match '/:username/toggle_follow', to: 'home#toggle_follow', as: 'toggle_follow'
This way both toggle_follow_path and toggle_follow_url will be created.
It needs to take in a :username param.
Try this:
toggle_follow_path(:username => "johndoe") # fill in the correct username.

I'm implementing the website. I got a problem for a search form. I upload my code, and what i want to ask is how to set the search 'path' through 'index' and 'historical' on homes_controller
Below, my code:
app/controllers/homes_controller
def index
#homes = Home.where(:category => 1).reverse
end
def historical
#homes = Home.where(:category => 2).reverse
end
app/views/layouts/application.html.erb
Below, this code is temporary code for now. I should change it.
<%= form_tag(homes_path, :method => 'get', id: "search-form" do %>
<%= text_field_tag :search, params[:search], placeholder: "검색" %>
<%= submit_tag "검색", :name => nil %>
<% end %>
Am not sure what you are supposed to do here
But as per the question - I can give a solution to your problem
Keep an instance variable in your controller actions - like this
app/controllers/homes_controller
def index
#homes = Home.where(:category => 1).reverse
#search_path = "path you want to give"
end
def historical
#homes = Home.where(:category => 2).reverse
#search_path = "path you want to give"
end
and in your layout you can use it like this
app/views/layouts/application.html.erb
<%= #search_path.present? %>
<%= form_tag(#search_path, :method => 'get', id: "search-form" do %>
<%= text_field_tag :search, params[:search], placeholder: "검색" %>
<%= submit_tag "검색", :name => nil %>
<% end %>
<% end %>
I have a modal that will serve as a disclaimer in my app and I need the link at the bottom of the modal that says "agree & continue" to toggle a boolean and input the time that the boolean was toggled. I have created the button as a form with hidden links but I cant seem to see how to make it submit the form AND redirect to the path i specify. Here is my link_to code now.
<% if current_user.user_record.blank? %>
<%= form_for :user do |f| %>
<% f.hidden_field :disclosure_acceptance, :value => true %>
<% f.hidden_field :disclosure_date, :value => Time.now %>
<%= link_to("Agree & Continue", user_steps_path(current_user), class: "btn btn-primary") %>
<% end %>
<% end %>
First, create a new method in your user_records_controller or at whichever controller action the form is displayed at:
def new
#user_record = current_user.build_user_record
end
Put this in your view:
<% if current_user.user_record.blank? %>
<%= form_for #user_record do |f| %>
<%= f.hidden_field :disclosure_acceptance, :value => true %>
<%= f.hidden_field :disclosure_date, :value => Time.now %>
<%=f.submit "Agree & Continue", class: "btn btn-primary") %>
<% end %>
<% end %>
Make a create action for the user_record that looks like this:
def create
#user_record = current_user.build_user_record(permitted_params)
if #user_record.save
redirect_to user_steps_path(current_user)
else
render :new
end
end
private
def permitted_params
params.require(:user_record).permit(:disclosure_acceptance , :disclosure_date) #etc
end
UPDATE
If you directly want to jump to the 'create' action, you can make your configuration like this:
Add a custom action to your routes:
post 'rate/:article_id' => 'user_records#create' :as => :create_user_record
#or whichever controller/action you wish
You should update the route on your form:
= form_tag create_user_record_path, :method=>'post' do
#etc
In order to create a user_record from the controller, you need to change things a little bit:
def create
current_user.user_record.create(:user_id => current_user.id, :disclosure_acceptance => params[:disclosure_acceptance] , :disclosure_date => params[:disclosure_date])
if current_user.user_record.save
#etc
end
Believe you can help me.
I'm trying to add new functionality to legacy code (Typo). But it seems that there is some problem about routing.
In the project routes are generated the following way:
%w{advanced cache categories comments content profiles feedback general pages
resources sidebar textfilters themes trackbacks users settings tags redirects seo post_types }.each do |i|
match "/admin/#{i}", :to => "admin/#{i}#index", :format => false
match "/admin/#{i}(/:action(/:id))", :to => "admin/#{i}", :action => nil, :id => nil, :format => false
end
My functionality is about merging articles. For that I've added new action in the /admin/content controller:
def merge
#some code here
end
A piece of a view partial (_form.html.erb) added by me:
<% if current_user.admin? and !#article.id.nil?%>
<div class=''>
<h4><%= _("Merge Articles") %></h4>
<%= label_tag :merge_with, 'Article ID' %><%= text_field_tag :merge_with, nil, :size => 20 %>
<%= button_to 'Merge', admin_content_merge_path(:id => #article.id) %>
</div>
<%end%>
This partial is rendered by another partial (_edit.html.erb)
<%= form_tag(form_action, :id => "#{form_type}_form", :enctype => "multipart/form-data", :class => className) do %>
<%= render :partial => "form" %>
<% end %>
And finally _edit.html.erb is rendered by view new.html.erb
<%= render "admin/shared/edit", { :form_type => "article", :form_action => { :action => "new", :id => #article.id , :class => ('autosave')} } %>
The problem is how to write a correct route for the controller action above which will allow me to render an edit page containing newly merged article. I wrote:
match "/admin/content/merge/:id" => "admin/content#merge",:as => 'admin/content/merge'
rake routes output:
admin_content_merge /admin/content/merge/:id(.:format) {:controller=>"admin/content", :action=>"merge"}
But the new or edit action is being invoked as I can see.
Apparently, my route is wrong, isn't it?
Could you please help me with this.
Thanks in advance!
Update
Up-to-date new.html.erb:
<% #page_heading = _('New article') %>
<%= render "admin/shared/edit", { :form_type => "article", :form_action => { :action => "new", :id => #article.id , :class => ('autosave')} } %>
<% if current_user.admin? and !#article.id.nil?%>
<%= form_tag "/admin/content/merge/#{#article.id}" do %>
<h4><%= _("Merge Articles") %></h4>
<%= label_tag :merge_with, 'Article ID' %>:
<%= text_field_tag :merge_with %><br />
<%= submit_tag "Merge" %>
<% end %>
<% end %>
Read the hint from the course:
HINT:Nesting is invalid in HTML.
That means that you can't nest form tags, don't put the form tag in another form tag, your nested form wont be able to do a correct action.
Since you have to put your code at the end of the page, try and see how to do it with having your merging form tag below the main edit article form tag. So basically you can find where the big form tag ends and put it below it.
Try to see if you can figure it out, and if not, don't hesitate to ask :)
Btw. I think everybody had some problem with this
<%= link_to (:controller => "company_stuff", :action => "index", :anchor => :menu), :class => 'links' do %>
<li>Terms of Use</li>
<% end %>
I am having difficulty linking a page which is on a different controller and also the link is an anchor. Basically the controller is called company_stuff the action is index and the anchor is called #terms
The problem was that the :controller :action :anchor was not being passed through as a hash, separate from the CSS class
Below is the solution
<%= link_to "Terms Of Use", {:controller => "company_stuff", :anchor => "terms"}, :class => "links" %>
I believe you can try something like this
<%= link_to index_company_stuff_path + "#terms", :class => 'links' do %>
<li>Terms of Use</li>
<% end %>
Or
<%= link_to index_company_stuffs_path + "#terms", :class => 'links' do %>
<li>Terms of Use</li>
<% end %>
Depending on your controller name and route.

I'm trying to observe a field that get generated inside a fields_for loop.
The thing is that the id of that field is generated dynamically.
_form.html.erb
<% form_for #exp, :url => {:action => "update"} do |f| %>
<% f.fields_for:patterns do |builder| %>
<%= render 'pattern_fields', :f => builder %>
<% end %>
<% end %>
_pattern_fields.html.erb
Pattern: <%= f.select(:LC_PATTERN, [['stripes', 'stripes'],
['dots', 'dots'],
['lines', 'lines'],
],{ :prompt => "Please select"}
) %>
<%= observe_field("------", :frequency => 1,
:with => "'id='+value", :function => 'alert(value)')%>
My question is how do i get the id of the field inside the fields_for tag.
I finally got it. Found this solution on the internet...Hope it might be of help to someone else.
In your application_helper.rb, add the following functions:
def sanitized_object_name(object_name)
object_name.gsub(/\]\[|[^-a-zA-Z0-9:.]/,"_").sub(/_$/,"")
end
def sanitized_method_name(method_name)
method_name.sub(/\?$/, "")
end
def form_tag_id(object_name, method_name)
"#{sanitized_object_name(object_name.to_s)}_#{sanitized_method_name(method_name.to_s)}"
end
You can then view the id of the fields generated inside 'fields_for' by using the following code:
<%=form_tag_id(f.object_name, :LC_PATTERN) %>
