问题描述
我需要将图像上传到我的电影收藏应用程序
i使用carrierwave来做到这一点()
步骤1我将gem'carrierwave','〜> 0.9'添加到我的Gemfile中,然后运行bundle
第2步:在rask db
之后安装Rails g上载器图像,然后在Rails g支架上将电影名称设置为movietype与我的电影模型中的railscasts
attr_accessible:name ,:moviestype,:image
mount_uploader:image,ImageUploader
在我的_form.html中。 erb
<%= form_for @filme,:html => {:multipart => true}做| f | %>
<%如果@ filme.errors.any? %>
< div id = error_explanation>
< h2<%=复数(@ filme.errors.count,错误)%>禁止保存该电影:< / h2>
< ul>
<%@ filme.errors.full_messages.each做| msg | %>
< li>%= msg%< / li>
<%end%>
< / ul>
< / div>
<%end%>
< div class = field>
<%= f.label:name%>< br>
<%= f.text_field:name%>
< / div>
< div class = field>
<%= f.label:电影类型%>< br>
<%= f.text_field:moviestype%>
< / div>
< div class = field>
< br>
<%= f.file_field:image%>
< / div>
< div class = actions>
<%= f.submit%>
< / div>
<%end%>
在show.html.erb
< p id = notice><%=通知%>< / p>
< p>
< strong>名称:< / strong>
<%= @ filme.name%>
< / p>
< p>
< strong>电影类型:< / strong>
<%= @ filme.moviestype%>
< / p>
<%= image_tag @ filme.image_url(:thumb)如果@ filme.image? %>
<%=链接到编辑,edit_filme_path(@filme)%> |
<%= link_to'Back',filmes_path%>
问题是它没有上传任何图像,但是电影名称和其他字段正在插入db.how我可以解决这个问题吗?需要快速帮助。
根据错误日志,您不允许图片
保存到数据库中。
在您的 FilmesController
中,您需要允许:image
作为
def filme_params
params.require(:filme).permit(:name,:moviestype,:image)##添加:image属性
结束

<%= image_tag @filme.image_url(:thumb) if @filme.image? %>
<%= link_to 'Edit', edit_filme_path(@filme) %> |
<%= link_to 'Back', filmes_path %>
problem is it didn't upload any image but film name and other fields are inserting to db.how can i fix this ?need quick help.
As per the error logs, you have not permitted image
to be saved in the database.In your FilmesController
, you need to permit :image
as
def filme_params
params.require(:filme).permit(:name, :moviestype, :image) ## Add :image attribute
end
