This form was working perfectly but I've not used it for a little while and I'm sure I've introduced an error somewhere, but I can't track what it might be. I have two other similar forms that submit to the same postgres db as expected. I can edit an existing record ok, so looks like it is just the new/create method I'm having problems with. The log doesn't actually show any error, it just redirects back to the new view:

看起来，根据您的控制器，您的表单提交正常但由于可能的验证而无法保存记录，在此页面上显示错误消息将告诉您错误的位置。我的猜测是数据库级别的唯一约束。
答案 1 :(得分：0)
根据您的日志
，您的表单是使用GET请求提交的Started GET "/coffeeshops/new?utf8=%E2%9C%93&authenticity_token=2A91tyxSfricbX03rLRcx9Vqm%2FuWQiZSgwwjmmScH3GrTe63RRBMTHs72%2F4cQaoXD5yC8jxY2GaRLgHvdhgCbg%3D%3D&coffeeshop%5Bname%5D=New+Coffee+Shop&coffeeshop%5Bsnippet%5D=Great+new+coffee+on+the+banks+of+the+thames&coffeeshop%5Bdesc%5D=lovely+coffee+shop+serving+Red+Brick+coffee&coffeeshop%5Barea%5D=central&coffeeshop%5Burl%5D=website.com&coffeeshop%5Bemail%5D=&coffeeshop%5Baddress%5D=&coffeeshop%5Bpostcode%5D=&coffeeshop%5Blocale%5D=central&coffeeshop%5Bphone%5D=123&coffeeshop%5Bimage_thumb_path%5D=photo.jpg&coffeeshop%5Bimage_path%5D=photo.jpg&coffeeshop%5Bbeans%5D=Red+Brick&coffeeshop%5Blong_black%5D=2.5&coffeeshop%5Btag_list%5D=tag&commit=Save+Coffeeshop" for 127.0.0.1 at 2017-06-12 17:46:34 +0100
因此，Rails将请求路由到控制器中的new操作，因为日志中的下一行说：
Processing by CoffeeshopsController#new as HTML
问题的关键在于您加载了通用符号:coffeeshop，而不是您在new操作中实例化的对象。
因为您只是使用符号而不是实际对象，所以Rails不知道您想要提交POST请求。
更改此内容：
<%= form_for :coffeeshop, url: coffeeshops_path do |f| %>
到此：
<%= form_for @coffeeshop do |f| %>
应该这样做。
