当我切换到使用form_with而不是form_标签时，Wicked_PDF不会下载
我注意到我的观点中有一个bug，在初次提交生成PDF后，我的表单无法提交，在研究过程中，我发现form_with是使用rails构建表单的推荐方法。我更新了我的表单，一切似乎都按照预期的方式运行，但现在PDF不像以前那样下载，只是在响应中呈现字符串而不生成文件。使用Wicked PDF和Rails 5.2.1。对不起，我错过了一些非常明显的东西 按预期使用form_tag pdf下载： 视图中的表格：当我切换到使用form_with而不是form_标签时，Wicked_PDF不会下载,pdf,ruby-on-rails-5,wkhtmltopdf,wicked-pdf,Pdf,Ruby On Rails 5,Wkhtmltopdf,Wicked Pdf,我注意到我的观点中有一个bug，在初次提交生成PDF后，我的表单无法提交，在研究过程中，我发现form_with是使用rails构建表单的推荐方法。我更新了我的表单，一切似乎都按照预期的方式运行，但现在PDF不像以前那样下载，只是在响应中呈现字符串而不生成文件。使用Wicked PDF和Rails 5.2.1。对不起，我错过了一些非常明显的东西 按预期使用form_tag pdf下载： 视图中的表格： <%= form_tag("download_pdf", format: :pdf, m
