我有一个可排序的表,它似乎工作正常,但是当我刷新页面时,订单略有关闭。基本上一切都是正确的,除了我移动的最后一行之外,它在正确的位置,它通常会在它应该占据的行下面恢复到一行。 (例如:如果我希望订单为1,4,2,3,我移动到的最后一个方框是方框4;刷新时我得到1,2,4,3)希望这是有道理的。
我的jquery:
jQuery ->
if $('#sortable').length > 0
table_width = $('#sortable').width()
cells = $('.table').find('tr')[0].cells.length
desired_width = table_width / cells + 'px'
$('.table td').css('width', desired_width)
$('#sortable').sortable(
axis: 'y'
items: '.item'
cursor: 'move'
sort: (e, ui) ->
ui.item.addClass('active-item-shadow')
stop: (e, ui) ->
ui.item.removeClass('active-item-shadow')
update: (e, ui) ->
item_id = ui.item.data('item-id')
console.log(item_id)
position = ui.item.index() # this will not work with paginated items, as the index is zero on every page
$.ajax(
type: 'POST'
url: '/stripboards/update_row_order'
dataType: 'json'
data: { stripboard: {stripboard_id: item_id, row_order_position: position } }
)
)
我的控制器:
class StripboardsController < ApplicationController
def index
@stripboards = Stripboard.rank(:row_order).all
end
def new
@stripboard = Stripboard.new
end
def edit
@stripboard = Stripboard.find(params[:id])
end
def create
@stripboard = Stripboard.new(stripboard_params)
if @stripboard.save
redirect_to stripboards_path
else
render 'new'
end
end
def destroy
@stripboard = Stripboard.find(params[:id])
@stripboard.destroy
redirect_to stripboards_path
end
def update_row_order
@stripboard = Stripboard.find(stripboard_params[:stripboard_id])
@stripboard.row_order_position = stripboard_params[:row_order_position]
@stripboard.save
render nostripboard: true # this is a POST action, updates sent via AJAX, no view rendered
end
private
# Use callbacks to share common setup or constraints between actions.
def set_stripboard
@stripboard = Stripboard.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def stripboard_params
params.require(:stripboard).permit(:stripboard_id, :title, :scene, :scene_type, :location, :description, :time, :pages, :characters, :production_id, :row_order_position)
end
end

我似乎认出来自http://benw.me/posts/sortable-bootstrap-tables/的代码。我让它为自己工作:)
在您重命名的update_row_order
函数中,我猜不到,nothing
符号为nostripboard
。对“事物”的发现和替换有点疯狂,或许?
尝试更新最后一行,以便函数读取如下:
def update_row_order
@stripboard = Stripboard.find(stripboard_params[:stripboard_id])
@stripboard.row_order_position = stripboard_params[:row_order_position]
@stripboard.save
render nothing: true # this is a POST action, updates sent via AJAX, no view rendered
end
render nothing: true
部分告诉Rails什么都不渲染 - 不使用视图,不使用模板,只需响应HTTP 200 OK状态。
由于我发现您的代码没有其他问题,请尝试此操作并向后报告。我还建议您在自己喜欢的浏览器中使用开发控制台/开发工具的网络选项卡(我知道Firefox和Chrome有一个,其他人没有真正尝试过)。它允许您嗅探AJAX发送的流量,并标记例如500个状态响应。此外,你应该阅读开发服务器的日志并在那里查找错误 - 我几乎肯定如果你看那里会有错误。
