views

问题 Is there any way to use slick with database views? When I run the standard code generator, nothing about views are listed. I also can't seem to find anything in the documentation mentioning the ability (or lack thereof) to do so. 回答1: Yes it is perfectly possible to use views, but you need to tweak code generation a tiny bit. See here for more specific information: https://github.com/slick/slick/issues/1022 (comment of "mobiworx") 回答2: If you follow the link provided by tfh, the following

问题 Is there actually any official strategy for creating and using views with EF6.1 Code First? I can reverse the database into Code First and get tables not views. I can import the database into Model First and get views and then do Generate DB from Model and my edmx is modified and the views are converted to tables. MSFT seems to have all but abandoned Model First, and the new Update 2 seems to have reverse engineering for Code First so I feel forced to convert to Code First but has the EF team

问题 Is there anyway I can make content in my Rails views editable by end-users? Such that they can make simple text changes on pages I permit them to without having me edit the HAML files myself? Thoughts? CLARIFICATION: I know about CMS systems, and I don't think that's entirely what I want. I want to maintain programatic control over my views, but there are sections that I want the user to be able to edit directly (for instance, I still need to populate the page with products, shopping cart,

问题 I am using an Translator object (custom class) to expose website texts (the object stores texts from the database). The Translator object is stored in the cache, in the Application_Start() function. My current use of the Translator object is: I have a MasterViewModel public class MasterViewModel { public Translator Translator = HttpContext.Current.Cache.Get("Translator") as Translator; } Every view has a viewmodel, that inherents from MasterViewModel public class RandomViewModel :

问题 I've created a custom view that loads its content from a nib, like this: /* PricingDataView.h */ #import <UIKit/UIKIt.h> @interface PricingDataView : UIView { UIView *contentView; } @property (nonatomic, retain) IBOutlet UIView *contentView; @end /* PricingDataView.m */ #import "PricingDataView.h" @implementation PricingDataView @synthesize contentView; - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { [[NSBundle mainBundle] loadNibNamed:@"PricingDataView" owner

问题 I am having an issue with the "Profile Checkboxes" module which stores custom profile fields comma separated. The issue is if I create a view to filter by a value. The SQL result ends up being something like this: ...AND (profile_values_profile_interests.value in ('Business and Investment'))... Which will not return any data since the value is stored like this: "Business and Investment, Case Law, Labor Law, Tax Law" I just need to adjust the SQL so that it is making sure the field contains

问题 I'm trying to create a data import mechanism for a database that requires high availability to readers while serving irregular bulk loads of new data as they are scheduled. The new data involves just three tables with new datasets being added along with many new dataset items being referenced by them and a few dataset item metadata rows referencing those. Datasets may have tens of thousands of dataset items. The dataset items are heavily indexed on several combinations of columns with the

问题 I'm trying to convert some of my django views over from function based views to class based views and I've run into a small problem. My OO is kind of weak and I think the problem is that I've lost track of where things are going. I have a custom login decorator that I need on the views so I have... First I have the View class from this example http://www.djangosnippets.org/snippets/760/ Then my view class looks like this... class TopSecretPage(View): @custom_login def __call__(self, request,

问题 My phpMyAdmin is missing pagination buttons when showing a view. My view have about 20.000 rows. How I can enable pagination buttons on views? 回答1: Essentially I have to enable row counting for views, by adding this line at the botton of the file config.inc.php (placed in the phpMyAdmin install directory): $cfg['MaxExactCountViews'] = 100000; 100000 is the maximum number of rows that you estimate the view will contain. This parameter is defaulted to zero, probably because the row counting
