python - how to display images from the ndb datastore using data URI scheme (via passing data to template and not having to make another request) -


I store a thumbnail image as a blob property of my entity. I am able to fix the pictures described here:

However, there is a need to get another request and get the ID from NDB. Since I already have the original unit available, when I present the IMG tag with the proper href attribute, would there be a way to render the image inline?

I have read the documentation for the Google Images API, but there is no such thing that will present my image in the format required to be included as a string. I go to a very large scale, but somehow everyone is suggesting ways to represent images from the above mentioned datastore. Being able to render images using the Yuri plan in my mind not only will the datastore get a request (perhaps with a memkach, but still still) but most importantly, the visitors of my page have a round across the ocean Will save you from traveling, which is fast enough to serve the page.

Many thanks for all your help!

Use the image service and the images will be served from a high speed image service, which is probably In case you can get closer to your end users, then you can organize yourself in GAE. 

  get_serving_url (blob_key, size = none, crop = false, safe_value = none)   
 
 one Returns the URL that works on the image.  
 This URL format allows dynamic resizing and crop, so you do not need to store different image sizes on the server.  Images are highly customized, with less latency than crooked infrastructure.    
 This also avoids another hit in the database, as you store the URL and serve the user.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
