사용자 인증을 사용하여 작은 Rails 앱을 구축하고 있습니다. 프로젝트를 구성하고, 작업을 추가하고, 댓글을 추가 할 수있는 앱입니다.
현재 사용자 인 경우 '프로젝트 시작'을 클릭하면 양식을 볼 수 있습니다. 그러나 양식을 제출하면 프로젝트 색인 (내가 원하는)으로 리디렉션되지만 프로젝트가 저장되지는 않습니다. 대신 오류 메시지가 있습니다. 어쨌든 코드로 볼 수 있습니다.

나는 이미 이전에 이와 같은 프로젝트를 수행 했으며이 문제는 발생하지 않았습니다. 그것이 내가 이해하지 못하는 이유입니다. 나는 확실히 뭔가를 놓친다.
알아낼 수 있기를 바랍니다. :) 아직 작업 중입니다 ...
Rails 4 이상을 사용 attr_accessor하는 경우 데이터베이스에 유지되는 속성을 사용해서는 안됩니다 . 이로 인해 해당 속성이 제대로 저장되지 않을 수 있습니다.
attr_accessor코드 줄을 제거 하고 대신 강력한 매개 변수를 사용하십시오.
def project_params
params.require(:project).permit(:name, :deadline, :description)
end
귀하의 코드에서 잊은 :description
또한 생성 작업이 설정되는 방식으로 인해 유효성 검사 오류가 표시되지 않습니다. 대신 다음과 같은 동작을 생성해야합니다. 저장에 실패하면 원래 양식이 다시 렌더링됩니다.
def create
@project = Project.new(project_params)
if @project.save
redirect_to projects_show_path, notice: 'Project successfully added'
else
flash[:alert] = 'An error ocurred adding your project. Please try again later'
render 'new'
end
end
또한 양식이있는보기에 오류 메시지를 표시해야합니다.
<% if @project.errors.any? %>
<ul>
<% @project.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
<% end %>
