ruby-on-rails - 表单提交而不执行任何操作轨道

Question

这是我的登录表格

<%= form_for Customer.new, url: {action: :login} do |f| %>
    <%= f.text_field :username,placeholder: 'Username or Email' %>
    <%= f.password_field :password,placeholder: 'Password' %>
    <%= f.submit 'Login' %>
<% end %>

这是我的控制器

def login
    username = params[:username]
    password = params[:password]
    unless username.blank? && password.blank?
      #My code doesn't entering to this block
    end
end

如果我提交表单它只是提交它不执行任何操作

如果你检查你的params哈希，你会发现这些键不存在。相反，您会看到它params[:custpmer]确实包含这些字段。这就是 rails 以样式构建参数的form_for方式。所以试试这个：

username = params[:customer][:username]
password = params[:customer][:password]
