I have to develop a module that is called news feed for posting new news feed to a website but when I am doing this I can not retrieve images from the database to view on the website. I have to get Title and Content but the image is not yet. 

anyone can help me how to fix

below is sample code that I use to retrieve title as well as content 


<table> 
    <tbody> 
        <t t-foreach = "posted" t-as = "news_feed" > 
            <td>                 <b>                     <t t-esc = "news_feed.news_feed_title" />                     <br/>                 </b>                 <t t-esc = "news_feed.news_feed_content" />                 <br/>             </td>         </t>     </tbody>

the field name is cover_image

Ivan Yang

The field name is cover_image in web.news.content ?

Can you try this

<img t-att-src="'/website/image/web.news.content/' + news_feed.id + '/cover_image'"/>

Hi,

There is a controller that allow users to fetch images from database to website:

http://yourdomain.com/website/image/your_model/record_id/field_name

For example:

http://yourdomain.com/website/image/product.product/1/image

Ivan
