我试图在单击按钮时显示一个弹出窗口,但是由于我总是收到Ajax方法错误消息,所以无法到达它。
我的弹出窗口应如下所示:
我试图用已经正常运行的弹出窗口的内容加载弹出窗口,并且该窗口正在运行。我可以通过我的网站显示选定的图像,但不能从弹出窗口中显示。
我想我的模型语法很好,因为我可以显示用户选择的图像,所以我的问题将出在我的Controller语法上。
我的控制器方法:
def pbbackground
progress_board = ProgressBoard.find(params[:id])
if params[:type] == "cover_image"
result = progress_board.cover_image.save
progress_board.save(validate: false)
end
end
我的模型参数用于添加cover_image
:
has_attached_file :cover_image,
:styles => { square: "200x200>", small: "400x400>", :large => "640x640>", :thumbnail => "400x400#",to_add: "362x270>", you_might_like: "260x160>" }
validates_attachment_content_type :cover_image, :content_type => ['image/jpeg', 'image/jpg', 'image/png', 'image/gif', 'image/bmp']
def assign_cover_image
if ci = params[:progress_board][:cover_image]
cover_image = ci
end
cover_image = File.open(cover_image_path)
self.cover_image = cover_image
self.save
end
我正在使用的Ajax方法:
function loadProgressForm(resource, id){
$(".form_loader").show();
if(resource == "new"){
url = "/progress_boards/new";
popup_name = "Make A Progress Board";
} else if (resource == "edit"){
url = "/progress_boards/" + id + "/edit";
popup_name = "Add/Remove Metrics";
} else if (resource == "pbbackground"){
url = "/progress_boards/" + id + "/pbbackground";
popup_name = "Add A Picture";
}
$.ajax({
url: url,
success: function(response, data){
$("#progress_board_form").html(response.html);
$("#progress_board_form").find('.modal-title').text(popup_name);
$(".form_loader").hide();
},
error: function(response, data){
alert("Error loading project form")
$(".form_loader").hide();
}
})
}
