mymodel.url is textproperty(string) which is something like this
<a href ='http://www.abc.com'><img src='http://xyz.com/></a><img src="http://www.abcdefd.com" />
In index.html, if I use {{mymodel.url}}, I will see the html code in my browser. In otherwords, jinja2 consider {{mymodel.url}} as string.
<a href ='http://www.abc.com'><img src='http://xyz.com/></a><img src="http://www.abcdefd.com" />
I want to see the image in my browser. How can I do it?
You have to indicate to jinja2 that this content is “safe” to display in a browser as HTML
