Form does not submit data - ruby-on-rails

Question

I have a form that has a few fields that should populate to my database which it doesn't. I am unsure why this is. I defined the parameters which fixed another error but my data is not being stored. My table name is users.
My controller:
Class LandlordPageController < ApplicationController
before_action :get_user
def get_user
#user = current_User
end
def index
end
def show
end
def create
#user = User.new(user_params)
#user.save
redirect_to profile_page_index_path
end
private
def user_params
params.require(:user).permit(:address, :cityResiding, :ssn, :birthDate, :gender, :phoneNumber)
end
end
My form:
<%= form_for :user do |f| %>
<div class="field">
<%=f.label :address, 'Current Address' %><br/>
<%= f.text_field :address, :required => 'required' %>
</div>
<div class="field">
<%=f.label :cityResiding, 'Current City' %><br/>
<%= f.text_field :cityResiding, :required => 'required' %>
</div>
<div class="field">
<%=f.label :phoneNumber, 'Phone Number'%><br/>
<%= f.telephone_field :phoneNumber, maxlength: 15, :required => 'required' %>
</div>
<div class="field">
<%=f.label :gender, 'Gender'%><br/>
<%= f.select :gender, ['',' Male', 'Female', 'Other','Prefer Not to Answer']%>
</div>
<div class="field">
<%=f.label :birthDate, 'Birth Date'%><br/>
<%= f.date_select :birthDate, order: [:month, :day, :year], :required => 'required'%>
</div>
<div class="field">
<%=f.label :ssn, 'Social Security Number' %><br/>
<%= f.text_field :ssn, maxlength: 9 %>
</div>
<div class="actions">
<%= f.submit "Submit Information" %>
</div>
<% end %>

EDIT: My form does submit data but this error is being thrown on save
NoMethodError in LandlordPageController#create
undefined method `save' for #<Array:0x0000000d883a08>

Answer 1

Instead of new I went with update and removed the save, because the new already executed saving the parameters and save was trying to save nil parameters. I was not creating a new user but meaning to add new parameters to an existing user. This is why the error occured. The full final code is below.
def create
respond_to do |format|
if User.update(user_params)
format.html { redirect_to profile_page_index_path, notice: 'Landlord application successfully submitted.' }
format.json { render :show, status: :created, location: #user }
else
format.html { redirect_to profile_page_index_path, notice: 'Landlord application was not successfully submitted.' }
format.json { render :show, status: :unprocessable_entity }
end
end
end

Answer 2

As has been said, the issue is probably validation errors.
If you mean to update the user, you will need to use the update method instead and pass the user to the form
form_for #user
That will send a PATCH request to the update method on the controller once the form is submitted.
def update
#user.update user_params
if ! #user.valid?
flash[:error] = #user.errors.full_messages
end
redirect_to profile_page_index_path
end
