Linkto() not working as expected

[David Mineer]

MG3

I have a linkto: <a href="#event.linkTo('firsttry','userid,profileid')#">First Try</a>

But the URL passed is http://test/index.cfm/firsttry/userid//profileid/

Shouldn't it put the values after the names between the //?  Should be:

http://test/index.cfm/firsttry/userid/1/profileid/dave

I do have a cfset userid = 1 and profileid = 'dave'

Am I misunderstanding how linkto() works?

Do you actually have event arguments named userid and profileid?

[David Mineer]

Well, that's where I am a little confused.  How do I get them into event if I don't pass them in the url.  Like I mentioned in the email, I set those on the page and normally would add them to the "a href" hyperlink and then they would be passed in the url and be available in the event scope.

Normally I would build he hyperlink like this http://test/index.cfm?event=firsttry&userid=#userid#&profileid=#profileid#

I assumed the linkto() would do that.

How do I get those values to the event scope?

[Jason Fisher]

If the variables do not already exist in the event when you call linkTo(), then you'll need to set them with event.setValue("userid", "1") and event.setValue("profileid", "Dave").

I wrote a custom URL Manager for this reason, which expands on the current one to keep its existing functionality, but if the 2nd argument is a structure instead of a string, it uses the key/value pairs from the structure instead of pulling the values out of the event context.

Here's my basic version: http://atuttle.pastebin.com/f31871859

So what do people do?  I must be thinking wrong here.  If you have a list of unique id's how do you set up those links with MG3:

<CFOUTPUT query="myQuery">
<a href="showdetail?myrecordid=#myQuery.id#
</CFOUPTUT>

Is Adam's solution the only way I can do this.  What would everyone else do?  I do feel that SES is very important.

Bump.

 

I would really like to hear how people handle this.  Forgive the bump.

 

How can I do the following with linkto():

 

<a href="Showdetail?myrecordid=#id#>Show Detail</a>

 

I use this type of link alot to pass variables.  Is it bad? Is there a better way that allows me to use linkto()?

 

Thanks,

[Sean Coyne]

The value ID must be set into the event first.

so if you have a local variable called ID already set, just set it in
the event right in the view.
<cfset id = 1 />
<cfset event.setvalue('id',id) />
<cfoutput><a href="#event.linkTo('some.event','id')#">Link</a></
cfoutput>

This will create a link like /?event=some.event&id=1

Thank you.  That makes sense.  For some reason I didn't realize you could mess with the event object in the view.

in MG3 the viewstate is gone. the event is the same in the controller
and in the view.

Ok, I played with setting the value in the event and that works.

But I don't think that would work if I was iterating over a query and had no idea which one of the rows the user was going to click on.  Since I have no idea which of the row id's to set in the event, I wouldn't be able to set the value into the event, right?

And I wouldn't be able to set the event on each row, because at the end the event.value would equal the value set from the last row of the query.

Still a little confusing.  Any ideas?

[Chris Blackwell]

Just set it for each row of the query

<cfloop query="myquery">

   <cfset event.setValue("id", myquery.id)>

   <cfoutput><a href="#event.linkTo('some.event','id')#">Link</a></cfoutput>

</cfloop>

admittedly it doesn't feel quite right doing it like this, but what problem does leaving the value of id equal to the last row of the query cause?

[David Mineer]

If that code loops over, say, 10 rows, and you set the id variable in event, aren't you just overwriting it each iteration of the loop?

<cfset event.setValue("id", '1')>
<cfset event.setValue("id", '2')>
<cfset event.setValue("id", '3')>

Wouldn't event.getValue() = 3 at this point?

[Chris Blackwell]

yes it would, but i dont see what the problem is. you set the value then you output the link, both within the loop...

2009/2/18 David Mineer <min...@gmail.com>

[David Mineer]

But if you click on 1 or 2 you still get 3. Wyen the page is done
rendering the value can only be equal to one thing, in this case 3. I
am confusing myself too and typing from my phone.

The view isn't rendered after you have done the loop. Each line will
be rendered with each iteration of the loop. 1 and 2 will have the
correct ID and 3 will say 3.
