Re: Cannot retrieve new records after saving them
I realized after, when reading again, that you were talking about a
loop. So the cacheQueries if affecting the getFoold.

Re: Cannot retrieve new records after saving them
THAT'S IT! cacheQueries = false was exactly the detail I was
missing! Phew!!! :)

Seems to me the method is 1) check to see if you have any records that match 'name' 2) if there is a match, get the id for that record 3) when you go to do a save, try setting $this->Foo->id = id of record to update 4) do your $this->Foo->save(...) and that should either create a new record or update an existing one Here's a stupid question for you: if getFooId is *always* returning a 0, then have you verified that getFooId is actually returning a correct value?

Re: Cannot retrieve new records after saving them
I think you misunderstand, having !$foold will avoid setting the id,
so it will call create and make a new record. If record exists, the
create is not called and your id is set... it will update.
Unless I am completely wrong concerning your problem, I think this
code will update as well as create new record if needed. Now that you
mention a "loop", using $this->Foo->cacheQueries = false might help.

Re: Cannot retrieve new records after saving them
This is actually just a reiteration of the same code I already
posted. Setting $newFoo['Foo']['id'] = 0; will have the same effect
as create(); as it will simply create a new row.

Re: Cannot retrieve new records after saving them
I guess I'm being too vague here. My original code is fine for doing
both inserts and updates. Let me illustrate the problem with more
code:
addFooToDb( 'Bob Jones', '04/05/2007 12:00:00' );
addFooToDb( 'Sam Smith', '04/05/2007 12:01:24' );
addFooToDb( 'Bob Jones', '04/05/2007 01:38:02' );
- CASE 1: There is already a record in the Foo table where name =
"Bob Jones", but nothing else.
In this case, the final contents of Foo will be something like this:
id nametext
1 'Bob Jones' '04/05/2007 01:38:02'
2 'Sam Smith' '04/05/2007 12:01:24'
This is the behavior I'm expecting. Sadly, this isn't always the
case...
- CASE 2: Table Foo is empty during first run of the script.
In this case, the contents of Foo should look exactly the same as
above. Instead, I'm seeing this:
id nametext
1 'Bob Jones' '04/05/2007 12:00:00'
2 'Sam Smith' '04/05/2007 12:01:24'
3 'Bob Jones' '04/05/2007 01:38:02'
This is entire due to the fact that even after a successful save for
the first record, getFooId( 'Bob Jones' ) will STILL RETURN '0',
rather than '1' as it should. Again, getLastInsertId() isn't
immediately helpful in this case because we insert a 'Sam Smith'
record between the two 'Bob Jones' instances.
Does that clarify the problem?

Re: Cannot retrieve new records after saving them
I think with all the posts you get the answer, should look like :
if( $fooId > 0 )
{
$newFoo['Foo']['id'] = $fooId;
}
else
$this->Foo->create();
$newFoo['Foo']['name'] = $name;
$newFoo['Foo']['text'] = $text;
if( $this->Foo->save( $newFoo ) )
$retVal = ($foold ? $this->Foo->field('id') :
$this->Foo->getLastInsertID());
}
}
return $retVal;

Well, that's what the example you had was doing anyway. :) Here's a
tweaked version.
function addFooToDb($name, $ext) {
$retVal = 0;
$fooId = $this->getFooId( $name );
if( $fooId > 0 ) {
$newFoo['Foo']['id'] = $fooId;
} else {
$this->Foo->create();
}
$newFoo['Foo']['name'] = $name;
$newFoo['Foo']['text'] = $text;
if( $this->Foo->save( $newFoo ) ) {
$retVal = $this->Foo->field('id');
}
return $retVal;
}
That *should* create a new record if getFooId() returns zero, and
update an existing record otherwise.

Re: Cannot retrieve new records after saving them
Almost there. I want addFooToDb() to either create a record if it
doesn't exist or update an existing record. What you provided here
will only update a record that's been found.
I should reiterate something with my example: The first time I run it
with the sample data, if there are no entries in the database table,
getFooId() will ALWAYS return 0, even if the entry has already been
successfully saved. After the script has been run, if I run it again
with the exact same data, it will always find the id for the first
record that was created.
Is that clearer at all?

Re: Cannot retrieve new records after saving them
Maybe just before the save do :
$this->Foo->create();

Aha! I think I may understand what the problem is. You don't want to
create new records, you want to simply update an existing one, right?
If that's the case, then what you need to do is make sure that you are
adding the primary key to your $data array and then executing a save.
Let me show you an example using your own function with a few
tweaks...
function getFooId( $name )
{
$foo = $this->Foo->find("Foo.name LIKE '%$name%'");
if ($foo) {
return $foo['Foo']['id'];
}
return 0;
}
function addFooToDb($name, $ext) {
$retVal = 0;
$fooId = $this->getFooId( $name );
if( $fooId > 0 )
{
$newFoo['Foo']['id'] = $fooId;
$newFoo['Foo']['name'] = $name;
$newFoo['Foo']['text'] = $text;
if( $this->Foo->save( $newFoo ) )
{
$retVal = $this->Foo->field('id');
}
}
return $retVal;
}
Try that out, that might fix the problem. My apologies if I have
misunderstood the problem.

Re: Cannot retrieve new records after saving them
This is very helpful, but only solves half of my problem.
The problem is that my input data has duplicates. For instance:
---
function getFooId( $name )
{
$conditions = "`dbFoo.name` LIKE '%$name%'";
$fooId = $this->Foo->field( 'id', $conditions );
if( !isset($fooId) || $fooId == false ) {
$fooId = 0;
}
return $fooId;
}
function addFooToDb( $name, $text )
{
$retVal = 0;
$fooId = $this->getFooId( $name );
if( $fooId >= 0 )
{
$newFoo['id'] = $fooId;
$newFoo['name'] = $name;
$newFoo['text'] = $text;
if( $this->Foo->save( $newFoo ) )
{
$retVal = $fooId;
if( $fooId == 0 ) {
$retVal = $this->Foo->getLastInsertId();
}
}
}
return $retVal;
}
---
Say I have an input file that takes in data that gets parsed into
$name and $text which I then pass to addFooToDb(). My uniqueness key
here is $name, and say we're assuming that the file is sorted by a
timestamp, and we want to overwrite existing entries with the same
name with any new ones that are encountered. Say our data looks
something like this:
-
"Bob Jones", "04/05/2007 12:00:00"
"Sam Smith", "04/05/2007 12:01:24"
"Bob Jones", "04/05/2007 01:38:02"
-
If there was no entry for "Bob Jones" when the loop starts, TWO
entries will be created, because each successive call to getFooId will
return '0' for the id, even though the entry has been created. The
getLastInsertId() method won't help here since it won't be the proper
reference once we add the "Sam Smith" record.
I'm trying to keep this as data independent as possible here, and
caching the name-to-id mappings in a hash of my own seems like an
unnecessary duplication of data, especially for a large data set.
Ideas?

There is no "caching of data" when it saves, and there is no command
to "force reads". Whenever I've wanted the id of a record I've just
saved, I've done the following:
// assume $this->data has stuff in it
if ($this->Foo->save($this->data)) {
$fooId = $this->Foo->getLastInsertId();
}
Then you go on your merry way doing whatever other work you wanted to
do, happy in the knowledge that $fooId contains the id of the record
you just created in the table associated with the Foo model.
Hope that helps.

Re: Cannot retrieve new records after saving them
Well, the query definitely runs, as the data exists in the table after the script completes. The problem is that I'm trying to access the new row in the table during the same run of the script immediately after running Model::save(), under the assumption that this command would immediately save the result in the database. Maybe it's just that the model itself is caching the data and I need a better way of forcing a read?

Re: Cannot retrieve new records after saving them
Hmmm... Conceptually, that'd be OK for the first time, but not
exactly what I would be looking for when I used the same $this->Foo-
>field('id', $cond); call for existing records that may have been
updated. How would I save the output of getLastInsertId() to the 'id'
value of the current instance of Foo so that $this->Foo->field('id',
$cond); would return it properly (called from a different method)?

Cannot retrieve new records after saving them
I'm working on a CakePHP script running from the command-line. I'm attempting to check for a record in table "foo", and if it doesn't exist, I add a new record using the Model::save() method. Afterwards, I immediately call Model::field() to try to capture the auto_incremented "id" field so that I can do extra work relating to that record. Problem is, when I call $this->controller->Foo->field( 'id', $conditions ); immediately after the save, it returns null. In fact, this happens every time for that record until the script has completed and is run a second time. I'm used to running scripts in Perl or TCL where when you make a database call, it completes immediately, so I'm confused by what seems to be some kind of caching of the data here. I can't seem to find any kind of flush() method to complete allow all of these things to be refreshed. Obviously I'm VERY new to CakePHP. Any insight here would be greatly appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Cake PHP" group.
