how to set column attributes in Squeryl-Record?

[Andrzej Skalski]

Hi,

I want to add column attributes (like "indexed" and "unique") to e-mail field of User (using squeryl-record protouser).

When I do it like described here http://squeryl.org/schema-definition.html

on(users)(s => declare(
    s.email.is(unique, indexed)
  ))

I get error

too many arguments for method apply: (index: Int)Char in class StringOps
[error]     s.email is(unique, indexed)

any clues?

Andrzej

Is this really your font-settings?

I find it not very easy to read...

This is probably Google Groups failing to be clever about pasting formatted text.

Any chance you're on a different version of Squeryl?

Thanks,

Antonio

Andrzej,

Check out the Lift Wiki entry on Squeryl. In particular, you’ll find this in the section on defining a schema:

The “is” function is ambiguous for records, so from version 2.3-SNAPSHOT on, you can use “defineAs” instead. Until then, you can also use “.~.is” if there is a compiler error.

I think that switching to defineAs will resolve your problem.

@Antonio:

I use

val liftVersion = "2.6.2"
  Seq(
    "net.liftweb"       %% "lift-webkit"        % liftVersion        % "compile",
    "net.liftweb"       %% "lift-mapper"        % liftVersion        % "compile",
    //"net.liftmodules"   %% "lift-jquery-module_2.6" % "2.8",
    "net.liftweb"       %% "lift-record"            % liftVersion,
    "net.liftweb"       %% "lift-squeryl-record"    % liftVersion,...

@David:

I tried

on(users)(s => declare(
    s.email.~is(unique, indexed)
  ))

and I have error:

value ~ is not a member of net.liftweb.record.field.EmailField[code.model.User]
[error]     s.email.~is(unique, indexed)

[David Whittaker]

Andrzej,

That’s because it would be .~.is, the initial .~ forces an implicit conversion to the type on which the .is method exists. Or, you could just do what I suggested in the first place and use defineAs :)

[Andrzej Skalski]

thanks for all the help, but I still can't get it working

for

on(users)(s => declare(
    s.email.~.is(unique, indexed)
  ))

I have

value ~ is not a member of net.liftweb.record.field.EmailField[code.model.User]

[error]     s.email.~.is(unique, indexed)

and for

  on(users)(s => declare(
    s.email defineAs(unique, indexed)
  ))

I have:

value defineAs is not a member of net.liftweb.record.field.EmailField[code.model.User]
[error]     s.email defineAs(unique, indexed)

Andrzej

[David Whittaker]

Hm.  Both of those methods should be available via implicit conversion.  Do you have imported net.liftweb.squerylrecord.RecordTypeMode._  first?

[Andrzej Skalski]

no, and that was the problem. Thank you.

Kindest Regards
