Hello!
Sorry for this question but I can't find my error!
In my Project I have my model called "team".
A User can create a "team" or a "contest".
The difference between this both is, that contest requires more data than a normal team.
So I created
the columns in my team table.
Well... I also created a new view called create_contest.html.erb :
<h1>New team content</h1>
<% form_for @team, :url => { :action => 'create_content' } do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :name %><br />
<%= f.text_field :name %>
</p>
<p>
<%= f.label :description %><br />
<%= f.text_area :description %>
</p>
<p>
<%= f.label :url %><br />
<%= f.text_fiels :url %>
</p>
<p>
<%= f.label :contact_name %><br />
<%= f.text_fiels :contact_name %>
</p>
<p>
<%= f.submit 'Create' %>
</p>
<%
end %>
In my teams_controller, I created following functions:
def new_contest
end
def create_contest
if @can_create
@team = Team.new(params[:team])
@team.user_id = current_user.id
respond_to do |format|
if @team.save
format.html { redirect_to(@team, :notice => 'Contest was successfully created.') }
format.xml { render :xml => @team, :status => :created, :location => @team }
else
format.html { render :action => "new" }
format.xml { render :xml => @team.errors, :status => :unprocessable_entity }
end
end
else
redirect_back_or_default('/')
end
end
Now, I want on my teams/new.html.erb a link to "new_contest.html.erb".
So I did:
<%= link_to 'click here for new contest!', new_contest_team_path %>
When I go to
the /teams/new.html.erb page, I get following error:
undefined local variable or method `new_contest_team_path' for #<ActionView::Base:0x16fc4f7>
So I changed in my routes.rb, map.resources :teams to map.resources :teams, :member=>{:new_contest => :get}
Now I get following error: new_contest_team_url failed to generate from {:controller=>"teams", :action=>"new_contest"} - you may have ambiguous routes, or you may need to supply additional parameters for this route. content_url has
the following required parameters: ["teams", :id, "new_contest"] - are they all satisfied?
I don't think adding :member => {...} is
the right way doing this. So, can you tell me what to do? I want to have an URL like /teams/new-contest or something.
My next question: what to do (after fixing
the first problem), to validate presentence
of all fields for new_contest.html.erb? In my normal new.html.erb, a user does not need all
the data. But in new_contest.html.erb he does. Is there a way to make a validates_presence_of only for one action (in this case new_contest)?
UPDATE:
Now, I removed my :member part from my routes.rb and wrote:
map.new_contest '/teams/contest/new', :controller => 'teams', :action => 'new_contest'
Now, clicking on my link, it redirects me to /teams/contest/new - like I wanted - but I get another error called:
Called id for nil, which would mistakenly be 4 -- if you really wanted
the id
of nil, use object_id
I think this error is cause
of @team at <% form_for @team, :url => { :action => 'create_content_team' } do |f| %>
What to do for solving this error?
