I would like to use llblgen to generate other project and class files.

For example model (CustomerModel)

But how do i

• Create custom method that remains in the class after code generation. (No partial class) (Custom method Fullname -> returns first and last name)

• If i add attribute for 1 new property for example regex, how do i keep that attribute after code generation ?

• When i add new field in SQL server table, it's automaticly added in my classfile.

• When I create 1 condition in template -> result is empty line, How can i avoid that ?

thanks

I assume you are using LLBLGen v.4.x

•Create custom method that remains in the class after code generation. (No partial class) (Custom method Fullname -> returns first and last name)

I wonder why don't want to use partial files, but anyway, there are custom code regions in the generated class files.

•If i add attribute for 1 new property for example regex, how do i keep that attribute after code generation ?

You can define attributes in the LLBLGen Designer.

•When i add new field in SQL server table, it's automaticly added in my classfile.

There is a setting for that "Add new fields after refresh " in the Proejct Properties\Catalog Refresher, But you need to refresh the Catalog, of-course.

•

When I create 1 condition in template -> result is empty line, How can i avoid that ?

Could you please explain this one in more details.

Here is what i would like to have / do:

Step 1 (Create model) in my template i get info from the entity to add attributes

[Display(Name = "<[EntityFieldName]>", ResourceType = typeof(Resources.Resources))]         
<[If Not IsNullable]>[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "<[EntityFieldName]>_Required")]<[EndIf]>
<[If IsStringField]>[StringLength(<[FieldMaxLength]>, ErrorMessageResourceName = "<[EntityFieldName]>_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]

i can create this

 public class CustomerModel
    {
        [Display(Name = "FirstName", ResourceType = typeof(Resources.Resources))]
        [Required(ErrorMessageResourceName = "FirstName_Required", ErrorMessageResourceType = typeof(Resources.Resources))]
        [StringLength(255, ErrorMessageResourceName = "FirstName_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]
        public string FirstName { get; set; }

        [Display(Name = "Surname", ResourceType = typeof(Resources.Resources))]
        [Required(ErrorMessageResourceName = "Surname_Required", ErrorMessageResourceType = typeof(Resources.Resources))]
        [StringLength(255, ErrorMessageResourceName = "Surname_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]
        public string Surname { get; set; }
    }

So far so good.

Step 2: (add custom content) Know i would like to add this with llblgen generation (i know that we can use of partial classes here.)

public string GetFullName()
        {
            return string.Format("{0} {1}", FirstName, Surname);
        }

Step 3: (add new field email)

        [Display(Name = "EmailAddress", ResourceType = typeof(Resources.Resources))]
        [Required(ErrorMessageResourceName = "EmailAddress_Required", ErrorMessageResourceType = typeof(Resources.Resources))]
        [StringLength(255, ErrorMessageResourceName = "EmailAddress_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]
        public string EmailAddress { get; set; }

but after generation i would like to add custom email validation attribute.

[RegularExpression(@"^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$", ErrorMessageResourceName = "EmailAddress_Regex", ErrorMessageResourceType = typeof(Resources.Resources))]

But can you generate code each step with llblgen with parts that are custom added.

 public class CustomerModel
    {
        [Display(Name = "FirstName", ResourceType = typeof(Resources.Resources))]
        [Required(ErrorMessageResourceName = "FirstName_Required", ErrorMessageResourceType = typeof(Resources.Resources))]
        [StringLength(255, ErrorMessageResourceName = "FirstName_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]
        public string FirstName { get; set; }

        [Display(Name = "Surname", ResourceType = typeof(Resources.Resources))]
        [Required(ErrorMessageResourceName = "Surname_Required", ErrorMessageResourceType = typeof(Resources.Resources))]
        [StringLength(255, ErrorMessageResourceName = "Surname_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]
        public string Surname { get; set; }
        
        [Display(Name = "EmailAddress", ResourceType = typeof(Resources.Resources))]
        [Required(ErrorMessageResourceName = "EmailAddress_Required", ErrorMessageResourceType = typeof(Resources.Resources))]
        [StringLength(255, ErrorMessageResourceName = "EmailAddress_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]
        [RegularExpression(@"^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$", ErrorMessageResourceName = "EmailAddress_Regex", ErrorMessageResourceType = typeof(Resources.Resources))]
        public string EmailAddress { get; set; }
        
    
    public string GetFullName()
        {
            return string.Format("{0} {1}", FirstName, Surname);
        }
}

Is this possible or are these limitations of LLBLGen.

If there is an other way to get this result please let me know .

I don't know exactly in what of your 3 steps you have problem with. It seems that you don't know how to manage the step 3.

Anyway, you can do all of that, please take a look at the attribute system, you can add them at top level (all entities, all fields, etc) or specific by each entity/field/navigator. This should solve it.

This is an example of using MetaData annotations for validation purposes, using MVC4 and partial classes: http://llblgen.com/tinyforum/Messages.aspx?ThreadID=18673&StartAtMessage=0&#104946

Can you please give me an example please for attribute.

I can not find any good example.

(even in the current templates from LLBLgen)

Here i found some TDL statements http://www.llblgen.com/documentation/4.0/SDK/hh_start.htm

<[Foreach CustomProperty Argument Separator]> text <[NextForeach]>

Is it possible to debug your template ?

you can hit F7 and there is a debug button ...

thanks

Did you check the zip of the example in the link I posted? http://llblgen.com/tinyforum/Messages.aspx?ThreadID=18673&StartAtMessage=0&#104946

Yes i used your template but it does not give me any information what i need.

please create 1 template and paste this inside it.

using System;
using System.ComponentModel.DataAnnotations;

namespace <[RootNamespace]>.DTO
{       
        public  class <[CurrentEntityName]>Model
        {
            <[Foreach EntityField]>
            [Display(Name = "<[EntityFieldName]>", ResourceType = typeof(Resources.Resources))]
            <[If Not IsNullable]>[Required(ErrorMessageResourceName = "<[EntityFieldName]>_Required", ErrorMessageResourceType = typeof(Resources.Resources))]<[EndIf]>
            <[If IsStringField]>[StringLength(<[FieldMaxLength]>, ErrorMessageResourceName = "<[EntityFieldName]>_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]<[EndIf]>
            //[RegularExpression(@"XXXXXX- REGEX -XXXXXX", ErrorMessageResourceName = "<[EntityFieldName]>_Regex", ErrorMessageResourceType = typeof(Resources.Resources))]
            public <[TypeOfField]> <[EntityFieldName]> { get; set; }    

            <[NextForeach]>
        }   
}

Please look at the included file. you will see that line 11, 39, 53, 60 is empty because it's not a string.

line 24 is empty because it's not required.

What i would like to do is: Remove the empty lines because the condition is 1line. add condition to show regex or not.

is it possible or not ?

I think I'm kind of lost with your last post and the beginnings of this thread. Mmm, Could you please try to explain the very crucial problem again?

OK, no problem

First of all i can now create generated files with llblgen.

But the result is not what i would like to have.

I have a template where my model is created with attributes on each property.

I use the foreach entityfield to walk to all fields.

On each of that field i add Display attribute. (for translation)

If the field "is required" add the Required attribute. [Required]

But i noticed that when it's not required it shows 1 empty line.

My generated code:

[Display(Name = "AddressLine2", ResourceType = typeof(Resources.Resources))]
            
[StringLength(60, ErrorMessageResourceName = "AddressLine2_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]
//[RegularExpression(@"XXXXXX- REGEX -XXXXXX", ErrorMessageResourceName = "AddressLine2_Regex", ErrorMessageResourceType = typeof(Resources.Resources))]
public System.String AddressLine2 { get; set; } 

How can i avoid for "the required condition" returning empty line?

My Template condition:

<[If Not IsNullable]>[Required(ErrorMessageResourceType = typeof(Resources.Resources), ErrorMessageResourceName = "<[EntityFieldName]>_Required")]<[EndIf]>

Let's start with this question first. :-)

Let's start with this question first. :-)

Ok, to remove the blank line, remove the end line return, I mean, put together the previous statement or the next one, as if they were both together. Play with it, and see similar templates in the built-in LLBLGen template files.

I found the solution.

If you write multiple conditions you have to do it like this:

[Display(Name = "<[EntityFieldName]>", ResourceType = typeof(Resources.Resources))]<[If Not IsNullable]>
            [Required(ErrorMessageResourceName = "<[EntityFieldName]>_Required", ErrorMessageResourceType = typeof(Resources.Resources))]<[EndIf]><[If IsStringField]>
            [StringLength(<[FieldMaxLength]>, ErrorMessageResourceName = "<[EntityFieldName]>_StringLength", ErrorMessageResourceType = typeof(Resources.Resources))]<[EndIf]>

After the condition enter "the character newline." example: <[EndIf]><[If IsStringField]>Newline here <[EndIf]>

Thanks for the tip btw.

I have my next question: How do i create custom conditions: for example:

if Entity field contains Email or Phone then

end if

There is not TDL token for that. You can write your own if you extend the TDL system.

Other option is: use a custom Settings to mark a field like "this is email", and use that to discriminate in your template:

 <[If Not SettingValueEquals ElementType SettingName QuotedString]>
text
<[EndIf]>

Or, use lpt templates.
