Getting a NoMethodError for user_id, but only on deploy (Rails)

This is working perfectly in production, but keeps messing up on deploy. Strange thing is that I have another model set up similarly with the same code, and it works fine on deploy.


def new
@task =

def create
@task =
@task.user_id = current_user[:id]
respond_to do |format|
format.html { redirect_to line_url(@task.lines_id), notice: 'Task was successfully created.' }
format.json { render :show, status: :created, location: @task }
format.html { render :new }
format.json { render json: @task.errors, status: :unprocessable_entity }

# Use callbacks to share common setup or constraints between actions.
def set_task
@task = Task.find(params[:id])

# Never trust parameters from the scary internet, only allow the white list through.
def task_params
params.require(:task).permit(:title, :description, :priority, :lines_id, :scene, :icon, :icon_color, :fulltext, :doclink, :user_id)

Meanwhile, in production, there is no issue with the commit:

I double checked to make sure I had run rake db:migrate on deploy.

I do not think it is an issue with current_user as I am definitely logged in as a user – I would not even be able to access the new form as I'm requiring current_user to view the form.

Really appreciate any insight you might have.


I suggest to add user_id as hidden field in new form like :

<%= f.hidden_field :user_id, %>

OR a better way to do it like :

@task =

as it is a better approach & will avoid this error situation.
