i'm new to rails , i'm tring to write spec test for controller method create and I can't figure out how to pass params users to get method. here is create method for project controller
def create
@project = Project.new(project_params)
@project.creator = current_user
byebug
if params[:project][:users].any?
byebug
params[:project][:users].reject!(&:empty?)
@project.enrolled_user = User.find( params[:project][:users])
end
byebug
authorize @project
respond_to do |format|
if @project.save
format.html { redirect_to @project, notice: 'Project was successfully
created.'}
format.json { render :show, status: :created, location: @project}
else
format.html { render :new}
format.json { render json: @project.errors, status: :unprocessable_entity}
end
end
end
project_spec.rb
context "post create" do
it "creates a new project" do
get :new
byebug
post :create,params: { user: user.id }
byebug
expect(project1.creator).to eq(user)
expect(enrolled_user.user_id).to eq(user1.id)
expect(response).to be_successful
end
end
terminal
1) ProjectsController post create creates a new project
Failure/Error: if params[:project][:users].any?
NoMethodError:

You really need a system test rather than a controller test to achieve your requirement to test the functionality you describe here. So Rspec coupled with Capybara will allow you to do things like this
So use rails g rspec:system project and do tests like
it "Can create a project" do
administrator_sign_in #some system test helper that creates a user and logs a user in if needed, there are plenty of examples on how to do helpers like this.
visit '/admin/projects'
click_link "New"
#save_and_open_page #Uncomment this if you want to see what your form fields are, unstyled, can be very useful when trying to see what to fill in and what button and links to press and click
fill_in "Name", with: "New project"
fill_in "Other project fields", with: "Some Data"
page.check("Name of a boolean field") #check a checkbox
click_button("Create Project")
project = Project.find_by name: "New project"
expect(current_path).to eq("/admin/projects/#{project.id}")
expect(page).to have_content("Project was successfully created")
expect(project.name_of_boolean_field).to be true
end
