Re: [Zope] Squid ESI
I'm reviving this thread from 2006 hoping to hear news about current ESI usage in the Zope community. Has anyone since then had success deploying sites with ESI-enabled caching? Using Squid, Varnish or any other product?

Re: [Zope] Z Search Interface returns numbers
You missed a step: you must use the Metadata tab of the ZCatalog to define which fields of the indexed objects should be returned with the results from the search. After you do that, you'll have to update the catalog (Advanced tab) and then regenerate your search interface. For instance, to return the ids of the objects, add id as a metadata. If you'd like to show the URL of each item, there is no need to set metadata for that, since the records returned form the catalog have a method called getUrl which gives you that. So you can use record/getUrl, where record is the variable name used in the tal:repeat statement which invokes the catalog search results.

Re: [Zope] Object DB versus Relational DB
ZODB with Data.fs is optimized to fetch data. Inserts or updates have a lot of overhead. It's the price we pay for the excellent versioning features. Therefore, when the are many we have been avoinding ZODB even when the problem domain calls for an OODB We have implemented a highly hierarchical database for a Yahoo-like directory using a recipe found in the book SQL for Smarties, by Joe Celko, ISBN 1-55860-323-9 (see Chapter 26 - Trees). Celko's solutions allow for a hierarchy with unlimited levels and, amazingly, it does not require sub-selects or any other construct unsupported by MySQL. The rest of the book is filled with solutions to problems that test the limits of the relational database model.

I've got a lot parent-child relationships - OODB But, I also need to perform some queries on these records and link some to each other - more RDB. I'm not sure which way to follow. A hybrid solution isn't the best one, I think, because then you do twice the same work. ie. You've to create the parent-child relationship in the OODB (the site structure) and in the RDB (to perform correct queries). The RDB solution is possible, but since I need lots of parent-child relationships not the best one. The OODB is probably the best.

Re: [Zope] Reversing acquisition?
Thank you very much for the correction. However, after checking your Wiki references, I must say I still don´t understand the difference between context and containment (these are words that I naively used as synonyms in my message). In http://www.zope.org/Wikis/zope-dev/AcquisitionUsage we find: """ - Containment: Search the object, then its container, then the container's container, and so on. Ignore objects not in this chain. - Context: Search the objects in precisely the reverse of the order in which they were mentioned, so "A.B.C.D" is always searched in the order "D", "C", "B", "A". """ But for me, A.B.C.D means that A contains B; B contains C; and C contains D, so I don´t see the difference from the first definition. Maybe you are using the word "container" in a more restricted sense?

What you want is what Zope already does! That is how acquisition works: if /subfolder has no index_html, it will acquire that object from the root. But the DTML inside index_html will be rendered in the context (namespace) of the subfolder, so the desired effect will be achieved. Unfortunately it is not quite as simple as that. Infact, to say that that is how acquisition works is misleading. It is not how acquisition works, but if you are using DTML Methods then you can create the effect of that being the way it works. Let me explain. When you acquire an object, the acquisition method used is to first look at the containment of the object before the context of the object. So if you have the scenario described above, when you call /subfolder/ it fist looks for index_html inside subfolder, but it isn't there, so it looks in subfolders containing object, /, where it does find index_html. Now it executes index_html and finds a call to text_object_1. So it first looks inside index_html for text_object_1, but it can't find it, so it looks in the _containing_ object of index_html, /, and finds text_object_1. However, if index_html is a DTML Method then things are different, because a DTML Method does not have it's own namespace and isn't an object in it's own right - rather it is a method of the calling object. The problem with this *containment before context* is that in most cases it goes against what is trying to be achieved. In the example above, there may be very good reasons why index_html needs to be a document rather than a method - maybe it needs it's own properties, etc. The point is that most often, the important thing when calling an object is the *context* in which it is called, not the location in the object store where it happens to be located. As I have mentioned several times now on the list, I can't see any good reason why acquisition should use the containment before context method (refered to as Simplified Acquisition) and in my opinion it should be changed to use context before containment (refered to as Natural Acquisition). See http://www.zope.org/Wikis/zope-dev/AcquisitionUsage for some explanation of the different types of acquisiton, and http://www.zope.org/Wikis/zope-dev/AcquisitionFeedback for a summary of the problem as I see it - if you have opinions then do add them. Also, Patrick Lewis wrote: Try changing /index_html as follows: dtml-var standard_html_header table trtddtml-var "PARENTS[0].text_object_1" fmt=structured-text /td/tr trtddtml-var "PARENTS[0].text_object_2" fmt=structured-text /td/tr /table dtml-var standard_html_footer Basically force Zope to look in the current folder first. That is all well and good for solving this particular problem, but it crosses a threshold in terms of accessability to the person writing the code. For a 'non-programmer', writing dtml-var object is not too difficult or scary, but dtml-var "PARENTS[0].object" is a world apart and quite a scary place to be. It's complicated, it doesn't make a lot of sense and it makes doing what should be quite simple things inaccessible. I work with a variety of people here, some of whom have no problem at all with any of the above, but others for whom there is a definite bar
