Disabling automatic indexing in acts_as_ferret

Ruby Apps Ferret
1

I’d like to be able to enable/disable the automatic indexing of
documents acts_as_ferret does. Something like MyModel.disable_indexing
MyModel.enable_indexing would be perfect. I need this because I do some
indexing that requires visiting the parents of the model objects and my
import method imports the children first, so the information isn’t there
yet. I’d like to disable the indexing, do all the importing and then
manually index the documents. Having a MyModel#index would be great for
this too.

Is there anything of the sort?

Pedro.

there’s an instance variable @ferret_reindex that’s checked before the
indexing takes place.
Something like

def save_noindex
@ferret_reindex = false
save
end

in your model should save the record without reindexing it. The boolean
is set to true in the after_save handler again, so the next call to save
should reindex again. You may call ferret_update directly to reindex
without saving, too.

This doesn’t work because of this code:

def ferret_before_update
@ferret_reindex = true
end
alias :ferret_before_create :ferret_before_update

add to index

def ferret_create
logger.debug “ferret_create/update: #{self.class.name} : #{self.id}”
self.class.ferret_index << self.to_doc if @ferret_reindex
@ferret_reindex = true
true
end
alias :ferret_update :ferret_createe

This makes @ferret_reindex always true when ferret_create runs.

The boolean
is set to true in the after_save handler again, so the next call to save
should reindex again.

I’m guessing the development branch has after_ handlers instead of
before_.

You may call ferret_update directly to reindex
without saving, too.

This worked great.

Thanks,

Pedro.

right, the only way to avoid this seems to be overriding
ferret_beforee_update. I’ll have a look into this.

I’d like to be able to enable/disable the automatic indexing of

I miss this feature badly: I need to disable aaf at the model level,
before bulk-modifying the 150K rows of a table, and rebuilding the index
afterwards.

I wish I could write code like :

Account.disable_ferret
... modify all the accounts in bulk
Account.enable_ferret
Account.rebuild_index

Is there a best practice/semi-official hack to achieve this goal?

You can enable/disable AAF on the object level:

AdvancedUsage#Disablingautomaticindexing

I don’t understand why it’s done that way. Disabling indexing on the
class level would make a whole lot more sense.

There you go.

Cheers,

just override the ferret_enabled?(bool) instance method to check for a
class variable holding your class level disable-flag…

I know, but it’s ugly, and indirect, and really not the way to do it
for this kind of use cases : bulk change, bulk import, …

A class method is needed :

Model.disable_indexing

bulk change

Model.enable_indexing(true) # true => trigger a rebuild_index
