After creating an instance of an object, Rails redirects to the index of the object that it :belongs to
When I click the Save in /views/parts/new.html, I expect to end up on /
views/parts/show.html, but instead I end up in /views/projects/
index.html, with the wrong [flash] message.
I have:
++++++++++++++++
/models/project.rb
----------------------------
has_many :parts
++++++++++++++++
/models/parts.rb
----------------------------
belongs_to :project
++++++++++++++++
/controllers/parts_controller.rb
----------------------------
def new
@project = Project.find(params[:project_id])
@part = @project.parts.build
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @part }
end
end
def create
@project = Project.find(params[:project_id])
@part = @project.parts.build(params[:concept])
@part.user_id = @current_user
respond_to do |format|
if @concept.save
flash[:notice] = ''You have successfully defined a new part
for this project''
format.html { redirect_to part_path(@part) }
format.xml { render :xml => @part, :status
=> :created, :location => @part }
else
format.html { render :action => "new" }
format.xml { render :xml => @part.errors, :status
=> :unprocessable_entity }
end
end
end
++++++++++++++++
/views/parts/new.html
----------------------------
form_for(@project, @part) do |f|
----------------------------
So, when I click Save in that button, I expect to end up on /views/
parts/show.html, with a nice [flash] reading ''You have successfully
defined a new part for this project''. Instead, I end up on /views/
projects/index.html, with the [flash] message defined in the update
action in the projects controller.
What''s going on and how can I fix this?
Many thanks,
Steven.

If so, I''m not sure why it doesn''t blow up entirely, but anyway, that was the first thing that struck my eye. David -- David A.

Re: After creating an instance of an object, Rails redirects to the index of the object that it :belongs to
I''m an idiot. Perils of copy-pasting controllers and then starting at them cross-eyed at 11pm (local time). I made the two changes above (@concept and []) and it took the process forward. But now when I save, it seems to be trying to create a project as well as a part, as it runs my new project validations and complains about there being no project name, etc. Colin, the submit code is: submit_tag ''Save'', :name => ''save'' On Sep 13, 12:10 am, Colin Law <clan...-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org> wrote:> 2009/9/12 steven_noble <ste...-IeilculjuCusTnJN9+BGXg@public.gmane.org>: > > > > > > > When I click the Save in /views/parts/new.html, I expect to end up on / > > views/parts/show.html, but instead I end up in /views/projects/ > > index.html, with the wrong [flash] message. > > > I have: > > > ++++++++++++++++ > > /models/project.rb > > ---------------------------- > > > has_many :parts > > > ++++++++++++++++ > > /models/parts.rb > > ---------------------------- > > > belongs_to :project > > > ++++++++++++++++ > > /controllers/parts_controller.rb > > ---------------------------- > > > def new > > @project = Project.find(params[:project_id]) > > @part = @project.parts.build > > > respond_to do |format| > > format.html # new.html.erb > > format.xml { render :xml => @part } > > end > > end > > > def create > > @project = Project.find(params[:project_id]) > > @part = @project.parts.build(params[:concept]) > > @part.user_id = @current_user > > > respond_to do |format| > > if @concept.save > > flash[:notice] = ''You have successfully defined a new part > > for this project'' > > format.html { redirect_to part_path(@part) } > > format.xml { render :xml => @part, :status > > => :created, :location => @part } > > else > > format.html { render :action => "new" } > > format.xml { render :xml => @part.errors, :status > > => :unprocessable_entity } > > end > > end > > end > > > ++++++++++++++++ > > /views/parts/new.html > > ---------------------------- > > > form_for(@project, @part) do |f| > > What does the submit code look like? > > Colin > > > ---------------------------- > > > So, when I click Save in that button, I expect to end up on /views/ > > parts/show.html, with a nice [flash] reading ''You have successfully > > defined a new part for this project''.

Re: After creating an instance of an object, Rails redirects to the index of the object that it :belongs to
And with fresh morning eyes, I solved that too. (T''was another concept where it should have been part -- another victim of copy-pasting controller code.) s.
