参数缺失或值为空:用户 rails 4 [英] param is missing or the value is empty: user rails 4
问题描述
当我尝试提交注册表时，出现以下错误.参数缺失或值为空:用户
I am getting the following error, when i try to submit my registration form. param is missing or the value is empty: user
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation)
end
请求如下:
{"utf8"=>"✓",
"authenticity_token"=>"YX0+4AeWlGWJiQZgbhV9cxi6TUCoibZfwh95BrK9iCQ=",
"name"=>"asasa",
"email"=>"asasas@asas.com",
"password"=>"[FILTERED]",
"confirm_password"=>"[FILTERED]",
"commit"=>"Register"}
以下是我的观点
<%= form_tag users_path, class: "form-horizontal", id: "signupform" do %>
<%= end %>
推荐答案
那里没有 params[:user] ，这就是错误告诉你的.您是否希望您的参数看起来像这样?
there is no params[:user] there, that's what the error is telling you. Are you perhaps expecting your params to look like this?
{"utf8"=>"✓",
"authenticity_token"=>"YX0+4AeWlGWJiQZgbhV9cxi6TUCoibZfwh95BrK9iCQ=",
"user" => {"name"=>"asasa",
"email"=>"asasas@asas.com",
"password"=>"[FILTERED]",
"confirm_password"=>"[FILTERED]"
},"commit"=>"Register"}
(我添加了一些缩进以突出显示结构).
(i've added some indentation to highlight the structure).
如果是这样，那么您需要修改提交这些参数的表单.要么使用 form_for @user，它会自动将输入标签的 name 属性设置为 user[name], user[email] 等，或者自己手动设置字段的名称，为 user[name] 等.
If so, then you need to amend the form that submitted these params. Either use form_for @user, which will automatically set the input tags' name attributes to user[name], user[email] etc, or manually set the field's names yourself, to user[name] etc.
