I tried to update a post and it tells me “Target language was successfully updated” but actually as soon as I hit the update button, the post goes back to original. I can’t find any error messages in the log, anybody could help me?
The result when I run rake routes
project_target_langs GET /projects/:project_id/target_langs(.:format) target_langs#index
POST /projects/:project_id/target_langs(.:format) target_langs#create
new_project_target_lang GET /projects/:project_id/target_langs/new(.:format) target_langs#new
edit_project_target_lang GET /projects/:project_id/target_langs/:id/edit(.:format) target_langs#edit
project_target_lang GET /projects/:project_id/target_langs/:id(.:format) target_langs#show
PUT /projects/:project_id/target_langs/:id(.:format) target_langs#update
DELETE /projects/:project_id/target_langs/:id(.:format) target_langs#destroy
POST /projects/:project_id/target_langs/:id(.:format) target_langs#update
My controller code
def update
@project = Project.find(params[:project_id])
@targetLang = @project.targetLangs.find(params[:id])
respond_to do |format|
if @targetLang.update_attributes(params[:targetLang])
format.html { redirect_to project_path(@project), notice: 'Target language was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @project.errors, status: :unprocessable_entity }
end
end
end

I think there’s a simple problem here.
You have two links, one to :delete (which I guess works) and the other to :update (which doesnt work)
Simply put, in HTML an
<a>tag (which is whatlink_toreturns) will not submit a form.When you click “Update” in your example, the only parameter you are sending is the id.
Instead you should say
submit_tag("Update")This will submit the form, and all should be well.
