I've created a form so the user can add a new picture to the website catalog, but for some reasons it doesn't work. Once the form is filled out, I click on the 'Submit' button but nothing happens, I just stay on the same page (and I don't have any error message...). I don't think the error comes from my Controller since nothing happens when I add the raise keyword in my Controller's 'create' method.
I'm sure this is an amateur mistake... but I can't see what it is. Thanks for your help!
picture.rb / Picture model:
class Picture < ApplicationRecord
validates :name, presence: true
has_many_attached :photo
end
new.html.erb / Here is my form :
<%= form_for(@picture) do |f| %>
<div class="form-group">
<%= f.label :name, "Please indicate the name" %>
<%= f.text_field :name, class:"form-control", placeholder:"(mandatory field)" %>
</div>
<div class="form-group">
<%= f.label :description, "Add a description" %>
<%= f.text_area :description, class:"form-control" %>

pictures_controller.rb /

@picture = Picture.new
end

@picture = Picture.new(picture_params)
if @picture.save
redirect_to root_path(@picture), notice: "Picture was successfully created"
else
render :new

And here is the text I got on my local server console
Here is the HTML output of my form :

My routes :
Rails.application.routes.draw do
devise_for :users
# Pages routes
root to: 'pages#home'
get 'about', to: 'pages#about'
get 'portfolio', to: 'pages#portfolio'
get 'sketchbook', to: 'pages#sketchbook'
get 'shopping', to: 'pages#shopping'
# Pictures routes
resources :pictures
end
Not quite sure why this is happening, but form_for is deprecated, so you should replace it with form_with.
You can use a model, such as your @picture with form_with as described in the docs.
<%= form_with(model: @picture) do |form| %>
# fields
<% end %>
This should create a form DOM object that looks like this:
<form action="/pictures" method="post" accept-charset="UTF-8" >
<input name="authenticity_token" type="hidden" value="..." />
...
</form>
If for some reason it doesn't, you can always pass a method: :post in the form_with (ie. <%= form_with(model: @picture, method: :post) do |form| %>).
