mysql - Symfony i18n table: Ways to get fallback default value? -

-

I'm creating a city name table in MySQL with approximately 10K rows to be a Siemphonii i18n table. Basically, The default culture is N_US and every city in the table is the beginning of this culture. Over time, I would like to add only those cities in the table, which can have alternate names in different languages, such as "London (NAUS) / London (SES)", without repeating the data of every city Language in different tables

Now, what I think, Symphony will not automatically choose a fallback default city name if there is no translation for it. So I need to prepare a solution to do the following:

If translation exists, select it .... If not, then choose the default en_US city name.

So far it seems that I should use the COALESCE However, as I am not very familiar about it, I am thinking that to use it are lacking? I am asking this because I have to include this in the query of every city which is a very consistent action on my site.

Suggestions for any ideas, or better way to work, will be thankful too. Thank you.

Try something like this: 

  $ q = Doctrine_Query :: ('City C') -> () -> LeftJoin ('c.Translation ct with lang IN (?)', Array (array ('es_ES', 'en_US')) - & gt; executed ();

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
