Below is my code
def create(conn, %{"create_video" => video_params}) do
admin_id = get_session(conn, :admin_id)
with {:ok, name} <- parse_name(video_params['name']),
{:ok, video_file} <- parse_file(video_params['video'])
do
video_fields = %{name: name, video_location: video_file, admin_id: admin_id}
case Videos.create_video(video_fields) do
{:ok, video} ->
conn
|> put_flash(:info, "Video created successfully.")
|> redirect(to: Routes.video_path(conn, :show, video))
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, "new.html", changeset: changeset, error: nil)
end
else
{:error, error}->
render(conn, "new.html", error: error)
end
end
My template file
<%= form_for @changeset, @action, [as: :create_video, id: "product-form", class: "mt-5 mb-5 login-input", method: :post, multipart: :true], fn f -> %>
<%= if @changeset.action do %>
<div class="alert alert-danger">
<p>Oops, something went wrong! Please check the errors below.</p>
</div>
<%= end %>
<%= if @error do %>
<div class="alert alert-danger">
<p><%= @error %> </p>
</div>
<% end %>
<div class="form-group">
<%= label f, :name %>
<%= text_input f, :name, name: "create_video[name]",
placeholder: "Name", class: "form-control" %>
<%= error_tag f, :name %>
</div>
<div class="form-group">
<%= label f, :video_location %>
<%= file_input f, :video_file, name: "create_video[video]",
class: "form-control", placeholder: "Upload Video
" %>
<%= error_tag f, :video_location %>
</div>
<div>
<%= submit "Save", class: "btn btn-dark mb-2" %>
</div>
<% end %>
I can understand changeset assign is missing in
render(conn, "new.html", error: error)
So I did
render(conn, "new.html", error: error, changeset: nil)
render(conn, "new.html", error: error, changeset.action: nil)
Both are not working. How to fix this? Your help is greatly appreciated. Thanks
