如何在 rails 中使用 form_for 的日期选择器?
How to use date picker with form_for in rails?
我是 rails 的新手,有什么线索吗?如果你也能建议我读什么就更好了。
我正在将日期选择器插件添加到现有的 rails4 应用程序中。我发现 this plugin on Github. i followed the instruction and configured everything in my app. Visiting http://localhost:3000/bookings/new 看起来不错,但是我填写信息并提交后,出现错误:
ArgumentError in BookingsController#create
First argument in form cannot contain nil or be empty
booking_controller.rb:
def new
@booking = Booking.new
end
def create
@booking = current_user.bookings.build(booking_params) # Not the final implementation!
if @booking.save
flash[:success] = "You have submited the information successfully!"
redirect_to root_url
else
render 'static_pages/home'
end
end
new.html.rb
<%= form_for (@booking) do |f| %>
<%= render 'shared/errorbooking_messages' %>
<%= f.label :date_of_tour %>
<input data-provide="datepicker">
<%= f.label :hotel_name %>
<%= f.text_field :hotel_name, class: 'form-control' %>
<%= f.label :hotel_address %>
<%= f.text_field :hotel_address, class: 'form-control' %>
替换此输入字段
<input data-provide="datepicker">
来自
<%= f.text_field :date_of_tour, "data-provide" => 'datepicker' %>
希望对您有所帮助。
仅以此答案为基础。从 rails 4 开始,您还可以使用以下格式。
<%= f.text_field :date_of_tour, data:{ provide:'datepicker' } %>
