Thanks Fred. I haven't try using submit_to_remote, but I think you are
right.
I just changed the form back to normal form without ajax. This time the
"Publish" button works correctly but the "Save" button behaves weird.
The first time I click it, it saves the post. But after the post is
saved, if I click save again it will "Publish" the post. Why?
This is my controller:
def create
if params[:post][:id] != ""
@post = Post.find(params[:post][:id])
@post.update_attributes(params[:post])
else
@post = Post.new(params[:post])
end
if params[:commit] == 'Publish'
@post.published = true
if @post.save
flash[:notice] = 'Post was successfully published.'
redirect_to posts_path
else
render :action => :new
end
else
@post.published = false
if @post.save
flash[:notice] = 'Post was successfully saved.'
render :action => :new
else
render :action => :new
end
end
end
