How do I associate my current user that is signed in to my post on create?
My post model:
before_create :owner
belongs_to :user
def owner
self.user_id = current_user.id
end
But that dosent work because I cannot use the method current_user in model.
Here is my controller:
class PostsController < ApplicationController
before_filter :authenticate_user!
# GET /posts
# GET /posts.xml
def index
@posts = Post.all
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @posts }
end
end
# GET /posts/1
# GET /posts/1.xml
def show
@post = Post.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @post }
end
end
# GET /posts/new
# GET /posts/new.xml
def new
@post = Post.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @post }
end
end
# GET /posts/1/edit
def edit
@post = Post.find(params[:id])
end
# POST /posts
# POST /posts.xml
def create
@post = Post.new(params[:post])
respond_to do |format|
if @post.save
format.html { redirect_to(@post, :notice => 'Post was successfully created.') }
format.xml { render :xml => @post, :status => :created, :location => @post }
else
format.html { render :action => "new" }
format.xml { render :xml => @post.errors, :status => :unprocessable_entity }
end
end
end
# PUT /posts/1
# PUT /posts/1.xml
def update
@post = Post.find(params[:id])
respond_to do |format|
if @post.update_attributes(params[:post])
format.html { redirect_to(@post, :notice => 'Post was successfully updated.') }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => @post.errors, :status => :unprocessable_entity }
end
end
end
# DELETE /posts/1
# DELETE /posts/1.xml
def destroy
@post = Post.find(params[:id])
@post.destroy
respond_to do |format|
format.html { redirect_to(posts_url) }
format.xml { head :ok }
end
end
end
How do I build the association ? So, that the post user_id coloumn gets assigned the current_user.id
Add
@post.user = current_user
in your create action.
Or if you have has_many :posts
association on User
model do:
@post = current_user.posts.new(params[:post])
if @post.save
...
I would suggest creating your post through your user:
# in create
@post = current_user.posts.build(params[:post])
This would automatically fill in the user_id
for you.
