DataType attribute is used for formatting purposes, not for validation. I suggest you use ASP.NET MVC 3 Futures for email validation. Sample code: [Required] [DataType(DataType.EmailAddress)] [EmailAddress] public string Email { get; set; } If you happen to be using .NET Framework 4.5, there’s now a built in EmailAddressAttribute that lives in System.ComponentModel.DataAnnotations.EmailAddressAttribute.
No, you didn’t miss a general purpose class. I have a Range type in MiscUtil which you may be interested in – and it certainly makes for simple DateTime manipulation. Referring to Marc’s answer, I can’t remember whether this is a struct or a class – you’d be welcome to change it of course. It’s … Read more
Yes, I think you want make = Make.objects.get(pk=1) make.make_content_set.filter(published=True) or maybe make_ids = MakeContent.objects.filter(published=True).values_list(‘make_id’, flat=True) makes = Make.objects.filter(id__in=make_ids)
The definition of these terms is quite ambiguous. You will find different definitions at different places. Entity: An entity represents a single instance of your domain object saved into the database as a record. It has some attributes that we represent as columns in our tables. Model: A model typically represents a real world object … Read more
The best statement on the subject of Frameworks I’ve heard is due to Uncle Bob: A good Architecture allows major decisions to be deferred! Specifically: A good Architecture delays choosing a Framework! Another great piece to think about: MVC is not an Architecture! It is a Delivery Design Pattern. Watch his video – it is … Read more
As of Django 1.11, you can use CITextField, a Postgres-specific Field for case-insensitive text backed by the citext type. from django.db import models from django.contrib.postgres.fields import CITextField class Something(models.Model): foo = CITextField() Django also provides CIEmailField and CICharField, which are case-insensitive versions of EmailField and CharField.
You can use this simple script to do that. But you must specify the names of the output nodes. import tensorflow as tf meta_path=”model.ckpt-22480.meta” # Your .meta file output_node_names = [‘output:0’] # Output nodes with tf.Session() as sess: # Restore the graph saver = tf.train.import_meta_graph(meta_path) # Load weights saver.restore(sess,tf.train.latest_checkpoint(‘path/of/your/.meta/file’)) # Freeze the graph frozen_graph_def = … Read more
I have found that while my domain model gets me 85% of the way to having the fields I want, it has never covered 100% of the values I want on my view. Especially when it comes to permissions and whether or not a user should have access to certain portions of the view. The … Read more
A model field is already property, so I would say you have to do it the second way to avoid a name clash. When you define foo = property(..) it actually overrides the foo = models.. line, so that field will no longer be accessible. You will need to use a different name for the … Read more
Just change the first line as follows : include ActionView::Helpers that will make it works. UPDATE: For Rails 3 use: ActionController::Base.helpers.sanitize(str) Credit goes to lornc’s answer
