Not passing params to action with form_for - ruby-on-rails

Question

I can't figure out why my form is not passing params to the registration controller. I have a registration form that doubles as a login form using jquery and javascript. My second form (the last one) is supposed to send over registration info to the registration controller. Unfortunatly I keep getting wrong number of arguments (0 for 1). I'm not sure how I'm not passing the information in, any help is appreciated.

<div id="imageDisplay"></div>
<div class="login-switch">
<div id="login-div" class="button button-outline button-calm switches active-button">
LOG IN
</div>
<div id="signup-div" class="button button-outline button-calm switches">

</div>
</div>
<%= form_for(#user, url: sessions_path, html: {id: "sign-in-form"}) do |f| %>
<div class="list list-inset">

<%= f.submit "Log in", class: "button button-block button-calm" %>

#user = User.create(sign_up_params)
if #user.save
log_in #user
flash[:success] = "We Made it!"

flash[:error] = #user.errors
end
end

def sign_up_params
params.require.(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
end
end

Answer 1

Remove . after params.require:
def sign_up_params
params.require(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
end

Answer 2

The error says wrong number of arguments(0 for 1), it's because you didn't pass any argument in the require method, you added a . before the opening parenthesis for the argument, you need to remove it, because Ruby is executing (:user) as a method but its not. Fix this error by correcting the typo as dp7 mentioned in his answer
def sign_up_params
params.require(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
end
Hope that helps!

Answer 3

It should be like that :
def sign_up_params
params.require(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
end
