You should probably add a trailing slash here: "/sortdata/" instead of
"/sortdata". Django will redirect the browser to /sortdata/ by default
(see APPEND_SLASH) and your POST data will be lost.

Re: not allowing me to login to admin site
Hi! When you change the password with phpmyadmin, did you consider that passwords are not stored in plaintext, but as salted hashes? You can try to set it to this value: sha1$3a68b$7fbea95491a9d04e3cf647d5c8e675da69e1d458 This should set your password to 'passwort' (without apostrophes). Alternatively, if you have shell access, you can use the DB API to reset the password.

Is it?
Have a look inside manage.py:
"
try:
import settings # Assumed to be in the same directory.
except ImportError:
import sys
"
It imports your settings file; django-admin.py does no such thing.
Hence manage.py takes care of setting up your environment correctly
for the current project such as your PYTHONPATH, and it can find all
the modules (apps) in your project directory. That explains why you
get an ImportError: the whatever module isn't in your PYTHONPATH.
Hope that clarifies things.

Re: not allowing me to login to admin site
Sorry just to add I am a newbie. I looked up previous questions and
found:
"I'm greatly enjoying this excellent project.
However, I have a problem with users created through the admin web
interface being able to log into the admin site.
I get "Please enter a correct username and password." Even though all
users have "is_active" and "is_staff" set to True.
It's definitely *not* a typo/caps-lock thing.
I'm using MySQL. "
The answer was:
">>>from django.models.auth import users
>>> u = users.create_user('username', '[EMAIL PROTECTED]', 'password')
>>> u.is_staff = True
>>> u.save() "
I tried this from within my project folder and it gave me a traceback
folder. I am not very confident with shells etc. I am using ubuntu OS
and MYSQL 5.051

How to create field not stored in database, but visible in admin?
How to create a field that is not stored in database, but is visible in Django newforms-admin? (I'm assuming there is a way) I would like to define a field which acts as a kind of proxy. Setting and getting value of this field actually runs some defined operation (for example executes custom SQL query) and returns it's results. This field has a related form field which is visible in Django newforms-admin among the form fields for other fields of containing model. As I'm using newforms-admin, I could add the form field to the ModelForm of my model in ModelAdmin and define custom save method for this form, which would execute a defined operation. But I want to have this functionality in two my different projects, and this approach would not be DRY. So is there a way to create such model field? Or maybe there is a better way to achieve what I want? Please help. PS. Sorry for my bad English. I'm not a native speaker. If something is not decipherable to you, just ask.

If you're on Django 0.96 or a checkout of the development code,
there's special-case handling in the admin for creating users such
that the password will be properly set, as well as a special-case
editing view for changing passwords through the admin.
For manually creating users from Python code, the Django User model
has a manager with a special method -- create_user() -- which will
handle this for you, so doing:
from django.contrib.auth.models import User
u = User.objects.create_user('bob', '[EMAIL PROTECTED]', 'some_password')
will work.
For manually editing users from Python code, the User model defines a
method called 'set_password()' which also handles this for you:
from django.contrib.auth.models import User
u = User.objects.get(username='bob')
u.set_password('some_new_password')
u.save()
For bulk imports, you can currently rely on some backwards-compatible
hackery we do to support storing passwords as plain old MD5 hashes, by
which Django will transparently "upgrade" the stored password to a
(more secure) salted SHA1 hash the next time the user successfully
logs in.

(I'm assuming there is a way) A model "field" is something that is stored in the database, by definition. If it's not stored in the database, it isn't a "field". It is just a normal Python attribute or property method. I don't know how easy it is to include those types of things in newforms-admin Admin, but that's the area you have to look in.

How to change ordering of m2m-fields in newforms-admin?
Hello all, maybe there are some newforms-admin experts out there: What's the right way to change the ordering of ManyToMany-fields (displayed as select widgets) in newforms-admin? I need to change the ordering *without* changing the respective model class. Background: The default ordering of the contrib.auth User class was removed from trunk (see ticket #6089). But I need an ordererd user selection widget for my ManyToMany-fields relating to the User class. BTW, how can I replace the default widget for a specific field to be used in the newforms-admin form?

Re: determining model subclass
André, I'm assuming that you are using the Trunk version of Django because subclassing isn't supported in previous versions. Assuming that. You can either have Item be an Abstract class which does not act like a table but just a parent class containing common items. (this is not what you are trying...) Or Each sub class is a seperate model from Item (assuming this is what you want). From the documentation you should be able to do the following: items = Item.objects.all() for item in items: try: x = Item.task type = "Task" except: try: x = Item.event type = "Event" except: type = "Item" Do something pertaining to the item type I haven't tried this but according to the docs it should work You should also fill in the correct exception. I just don't know what it is. Hope it helps. Dave.

Sort a list of objects by an attribute of the objects
Ok i have a list of form fields, i want to sort the list by the ".label" of the fields. I have tried a many different ways but i cant seem to make this work.

Re: "ColorField"?
You'll want to check out django.db.models.fields, django.db.models.fields.subclassing, and django.core.validators as starting points for creating a new Field type with a custom validator. In addition, there's a js attribute for class Admin you can use to bring in the necessary JavaScript into admin (http://www.djangoproject.com/documentation/model-api/#js), or you can look into newforms-admin branch (soon to be trunk) for more options on custom admin pages.

Dave, I'm not familiar with formtools but if all you want to do is
prepopulate a form then you can use the initial={} keyword arg. This
probably doesn't help but ... you could do this in your view if you
want:
form = Form(initial={'user':u, ...})

Another trick is to use model_to_dict to pass in initial values :
from django.newforms.models import model_to_dict
...
f = Form( initial=model_to_dict(obj) )

How to use combined indices (esp. in fulltext queries)?
Hi,
I would need to do a query like
SELECT * FROM mytable WHERE match (a) against("+AAA" in boolean mode)
and match (b against("+BBB" in boolean mode)
and match (a,b) against("+AAA +BBB" in boolean mode)
If I would omit the last line (which seems to be redundant) I could do
this easily with the Django framework by
s.filter(a__search='AAA', b__search='BBB')
However it turned out that doing the query with the last line is far
more efficient for MySQL. By querying (a,b) it can query a combined
index which returns only very few rows which then are combined with
the other two AND statements. If I omit the combined index, the temp
table (for doing the AND statement) is far bigger. The speed gain is
about factor 100 - sometimes even more (yes: my tables are quiet large
and it is noticeable)
How would I do this in Django?
Thanks for your help.
Tobias.

elusive Post error
I was wondering if anyone else has ever run into this problem...
When filling out a form, I click submit and get a POST error claiming
that the page does not support POST. However, if I refresh the error
page, the request goes through, and all is happy.
I don't have much experience with web applications, so I'm not sure
where to start here. We're running on Apache and using SSL for
authentication, but I disabled SSL and the problem persists.
Here's my settings file anyway... any ideas?

Markup languages vs HTML
Hi, I'm working on some project, a part of which is a small blog app. All the blog posts are saved as HTML (using TinyMCE in admin). I was wondering, after reading some stuff about Markdown, what are pros and cons of each method, ie. saving posts with some markup language vs. html. I must admit, that I feel a bit uncomfortable saving html to the database - it just doesn't seem right to me. So, what is your opinion on this matter?

Grouping Items In Multiple Categories
Does anyone know of an elegant way in Django to group database items under 2 categories. For example I have a database model that contains the following information: State Committee_Type Committee When I send it out to the template, I need to be able to group each committee under its type and state so that it looks something like this: State 1: Committee_Type1: Committee1 Committee2 Committee_Type2: Committee1 Committee2 State 2: Committee_Type1: Committee1 Committee2 Committee_Type2: Committee1 Committee2 etc... I looked at the regroup tag but I can only get it to group the items by a single category, any help would be appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

one to one symmetric relationship
Hello, Thanks for your answer Malcom. My mistake was to suppose that one to one relationships were symmetric. Do you have an idea on how to design a symmetric one to one relationship ? I tried with ForeignKey(unique=True) but it is not symmetric. I even tried ManyToManyField(unique=True), which is symmetric but not really unique in an object point of view. It is unique in a DB point of view. We can add (A,B) and (C,A) tuples in the m2m table, which creates multiple relationships A-B and A-C. Is it possible with existing fields ?

Yeah, give more than lip service to "simple simple simple". You say that then outline how you are reimplementing HTTP because you don't want to be "exposing the internal URLs" yet. I suggest spending an hour, a day learning about how your webserver(s) handle auth and start using it. My $.02US (only about .01 at today's rates) Baring that, option B is best since the code will at least be useful for tests. Where as the other options' code become mostly worthless once you start using real requests. -- Norman J. Harman Jr. Senior Web Specialist, Austin American-Statesman ___ You've got fun!

Re: Markup languages vs HTML
Hi Matic, I really think that html should not be saved on your database. Markup languages are more "human readable" and can be easily converted to HTML, if needed. And really, it just don´t look right :) Cheers and good luck. -- Rui --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Don't know about elegant, but something like this would work:
{% regroup committees by state as committee_state_list %}
{% for committee_state in committee_state_list %}
{{ committee_state.grouper }}
{% regroup committee_state.list by committee_type as committee_type_list %}
{% for committee_type in committee_type_list %}
{{ committee_type.grouper }}
{% for committee in committee_type.list %}
{{ committee.name }}
{% endfor %}

ProgrammingError: (2014, "Commands out of sync; you can't run this command now")
In a production site, all of a sudden while trying to edit the site
via the admin interface I get:
ProgrammingError: (2014, "Commands out of sync; you can't run this
command now")
This is when trying to access the record list: "/admin/core/pagina/"
This is only while trying to edit this one specific model ('pagina'),
I can edit the others without errors.
I dumped the database to my development server, and I get the same
error. It was working fine right before importing the DB from the
production server, so I'm thinking there's a problem in the actual DB.
I ran Optimize, Check and Repair on the DB in MySQL Administrator. No
dice.
I haven't updated or changed anything on either server. Development's
running XP, production Linux.

I often will create two(three) fields. body_markup -> "source" text in markup body_rendered -> body_markup rendered to html [markup_style] -> optional choice field that defines what markup body_markup is in Edit body_markup. Display body_rendered. Render body_markup to body_rendered on save(). body_rendered is probably a pre-optimization. But, I use it anyway.

connection.queries - show improper SQL?
When I look at generated sql from connection.queries, it doesn't show
any quotes around strings.
For example:
>>> from django.db import connection
>>> from django.contrib.auth.models import User
>>> User.objects.filter(username="bob")
[]
>>> connection.queries[-1]
{'time': '0.000', 'sql': u'SELECT `auth_user`.`id`,
`auth_user`.`username`, `auth_user`.`first_name`,
`auth_user`.`last_name`, `auth_user`.`email`, `auth_user`.`password`,
`auth_user`.`is_staff`, `auth_user`.`is_active`,
`auth_user`.`is_superuser`, `auth_user`.`last_login`,
`auth_user`.`date_joined` FROM `auth_user` WHERE
`auth_user`.`username` = bob ORDER BY `auth_user`.`username` ASC'}
>>>
As one would imagine, when I execute:
mysql> SELECT `auth_user`.`id`, `auth_user`.`username`,
`auth_user`.`first_name`, `auth_user`.`last_name`,
`auth_user`.`email`, `auth_user`.`password`, `auth_user`.`is_staff`,
`auth_user`.`is_active`, `auth_user`.`is_superuser`,
`auth_user`.`last_login`, `auth_user`.`date_joined` FROM `auth_user`
WHERE `auth_user`.`username` = bob ORDER BY `auth_user`.`username`
ASC;
It complains with "Unknown column 'bob' in 'where clause'".
It's obvious how I would change that code to execute properly, but I'd
like to know exactly what query django is building.
(for example you can get away with passing a number into a query
against a varchar, and that can affect the efficiency of complex
queries)
Is this Django-MySQL 5.x specific? Is this a full-on django bug?
Regards.

Re: Markup languages vs HTML
The important consideration is what is the best representation for your data? Since you are talking about user-edited content, you need to think about the user experience, and what data format is best for your users. The database concerns don't really matter after that. If you users need or expect to edit HTML, then you should offer that and store the HTML in the database. Don't be distracted by the fact that HTML is often generated from structured data: it can also be a perfectly reasonable data storage format itself. On the other hand, if your users would be more comfortable editing Markdown, then use that. The user experience concerns are far more important, and will dictate the data storage. --Ned.

newforms: how to make input widgets smaller
Hallöchen!
I use newforms.ModelForm to get a form from one of my models.
However, the HTML fields are all too wide. Okay, I could
re-define all fields that need narrower s like
class SixChamberChannelForm(ModelForm):
gas = forms.CharField(widget=forms.TextInput(attrs={"size": "10"}))
diluted_in = forms.CharField(widget=forms.TextInput(attrs={"size": "10"}))
class Meta:
model = models.SixChamberChannel
however, then I lose the information contained in max_length and
help_text in the model. How can I just put a "size" attribute to
the fields?
Tschö,
Torsten.

Transitioning old webapp to Django
Hi, I'm moving an old PHP & MySQL3 application to Django SVN with mysql5, and I've run into a problem. The passwords for the old user accounts were stored in the database and used the mysql PASSWORD() function for hashing. MySql 5 changed the hashing function, but kept the old hashing function under OLD_PASSWORD() for compatibility. I would like to have django use the OLD_PASSWORD() function for the user's first login, and then recreate the hash using the current PASSWORD() function. Does anyone know of a good way to have Django use the OLD_PASSWORD() function? It would be nice to use a modified version of contrib.auth, but I'm not sure if its possible.

The behavior you see stems from the fact, that different database backends
need different quoting and escaping of values. The SQL queries from
connection.queries
are not literally executed; the statements and the parameters get passed
separately to the backend as as good practice recommends.
What you see is not a Django bug then, but maybe not Django-MySQL specific
either. If you need to know more you'd have to dig into the django db or the
python-mysql source code.

Re: Django + tiny_mce
Thanks Chatchai.
Unfortunately, integration of tiny_mce still eludes me. It seems that
django is not looking in the proper directory for tiny_mce.js. But I
can't see why, despite generous off-list help from kind-soul Peter.
1) I've reviewed and documented my configuration below and would be
truly grateful if someone could point out the error or my way.
2) Also, at one point I though the problem might be due to improper
file permissions. So I've opened tiny_mce.js and change_form.html wide
open. Didn't help, but I suspect it may have created a security
problem. Can anyone tell me how to set the permissions correctly?
Lloyd
Review of tiny_mce configuration:
1) Bennett:p23
"In urls.py, add a new line..."
my urls.py *
from django.conf.urls.defaults import *
urlpatterns = patterns('',
# Example:
# (r'^cms/', include('cms.foo.urls')),
# Uncomment this for admin:
(r'^admin/', include('django.contrib.admin.urls')),
(r'^tiny_mce/(?P.*)$','django.views.static.serve',
{ 'document_root': '/home/lloyd/
django/media/jscripts/tiny_mce' }),
(r'', include('django.contrib.flatpages.urls')),
)
**
2) Bennett:p24
"Replace the /path-to-tiny_mce/..."
See above.
2a) Confirm path to tiny_mce
Entered in browser: http://192.168.1.4:8000/tiny_mce/tiny_mce.js
Browser returned: var tinymce={majorVersion:'3',minorVersion:'0.8',...
3) Bennett:p25
"So inside your templates directory, create an admin directory. Then
create a flatpages directory inside of admin and a flatpage
subdirectory inside of flatpages. Finally copy the change_form
template..."

total 4
-rwxrwxrwx 1 lloyd lloyd 3493 2008-07-08 02:16 change_form.html

{% load i18n admin_modify adminmedia %}
{% block extrahead %}{{ block.super }}
tinyMCE.init({
mode: "textareas",
theme: "simple"
});
5) Test
Enter in browser: 192.168.1.4:8000/admin/ and advance to change form.
Output of runserver:
[08/Jul/2008 15:37:57] "GET /admin/ HTTP/1.1" 200 4851
[08/Jul/2008 15:38:00] "GET /admin/flatpages/flatpage/ HTTP/1.1" 200

tiny_mce.js HTTP/1.1" 404 1780
Clearly django is looking for tiny_mce.js in wrong place.

# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
'/home/lloyd/django/templates',
8) QUESTION?
Why is django looking for tiny_mce in .../admin/flatpages/flatpage ?

I had tried and failed. At least Firefox ignores style="width: 3em"

Re: connection.queries - show improper SQL?

Parameter values won't necessarily be quoted correctly, since that is done by the database interface at execution time. The __str__ method just does a naive Python % operation, and doesn't try to quote the results.

Trying to understand project structure w/apps
Hi guys+gals, I'm new to django, and I'm trying to wrap my head around a project structure. I have a simple case that I'm thinking about, but can't put together a reasonable mental model for it. I've got a site that has a schedule component (events), and a news component (news items). So I can easily create two apps, one for events, and the other for news, and I can create varying ways to display these components. My problem is that when I start thinking about the homepage... where I'd like to display both some events, and some news items. I can't figure out how I would use templates to do such a thing... place both on the same page. Ideally, I would like to have a template that displays an event, and one that displays a news item. But I'm not sure how that would work, with both of them extending the same base template. I could, of course, create one app which has all of these models internal, which would let me easily pull them into a single template, but I would really rather not couple the two distinct models together in both the view and the templates. If someone could give me a few pointers in a direction they'd approach this problem, it would be greatly appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Calculating on generic view
Hey,
it helps :-)
but i have a little problem now. I try to add an attribute to each
element.
In the CLI ist works:
>>> from mysite.myapp.models import Mymodel
>>> list = Mymodel.objects.all()
>>> for elem in list:
... elem.kmph = elem.distance/elem.time
>>> list[0].kmph
45
But when i put this in a view, it don't work:
def myview(request):
list = Mymodel.objects.all()
for elem in list:
elem.kmph = elem.distance/elem.time
return object_list(request, queryset=list)
In the template i have a part something like this:
[...]
{% for elem in object_list %}
{{elem.distance}}
{{elem.time}}
{{elem.kmph}}
{% endfor %}
[...]
but the "kmph" is allways empty.
Any idea?
thanks so far...

Typically templates are so site specific that is doesn't make sense to
have templates in "apps". Templatetags can be handy.

I think you have a false idea that templates are tied to models somehow.
This is not the case.
I often create an app called "main" that includes stuff like index about
other "site" pages. The main index page often includes data from many
models. in main/views.py
from app import ModelOne
from app import ModelTwo
def index(request):
context = dict()
context["ones"] = ModelOne.objects.all()
context["twos"] = ModelTwo.objects.filter(somekey=somevalue)
render_to_response("main/index.html", context)

FieldError during a loop in the template and having a hell of a time
tracking down the problem.
The relevant part of the template is:
{% for m in p.members.all %}
{{m.get_profile.get_display_name}}{% if not forloop.last %},
{% endif %}
{% endfor %}
When I do the same loop in the shell I don't get any exceptions. Any
help is greatly appreciated, this is on trunk.
The code seems to choke on specifically one project (id 51) but I've
traced all the relations in the db that I could think of and don't see
any inconsistencies. But the template error is not consistent meaning
sometimes i get the exception and sometimes I don't so just trying to
clean things up where I can, starting with the model.

Okay, after some introspection (__dict__ rules) I found this
solution:
class SixChamberChannelForm(ModelForm):
def __init__(self, **keyw):
super(SixChamberLayerForm, self).__init__(**keyw)
self.fields["gas"].widget = forms.TextInput(attrs={"size": "10"})
self.fields["diluted_in"].widget = forms.TextInput(attrs={"size": "10"})
class Meta:
model = models.SixChamberChannel
I nobody sees possible unfortunate side effects here, I think that's
it.
Tschö,
Torsten.

Import issues since newforms-admin
Hi, There's an issue that arose as I upgraded an external app of mine to newforms-admin. I created the conventional admin.py, which does all the registration business, and did "import admin" in the module's __init__.py After I did that, I got some import errors at compilation time (or say, project's launching time): "ImportError: cannot import name MenuItem" "MenuItem" is in the external app (freshly upgraded to nfa), and the import that raises the error is made in the project's app. The external app was included at the top of the INSTALLED_APPS setting. Putting it at the end of INSTALLED_APPS solved the issue. I thought that the order didn't matter in INSTALLED_APPS. Have I missed something or have I possibly misconfigured my external app or my project's apps? Is that a known issue (and if so, what's the proper way around it?), or is that worth filing a ticket?

Re: Django + tiny_mce
Easy fix. Open your models.py and in the Class Admin section of the
model insert js = ['tiny_mce/tiny_mce.js', 'js/textareas.js'].
For example:
class Admin:
list_display = ('headline', 'author', 'pub_date', 'publish')
list_filter = ['pub_date']
save_as = True
js = ['tiny_mce/tiny_mce.js', 'js/textareas.js']
Save the model.
Stop and restart you apache server.
Login the Admin and verify the changes.

cursor.execute(my_custom_sql)
Seriously! Django is designed to cover maybe 80% of what SQL does. The
common stuff. And it provides you with access the the database cursor so
that you can do raw queries when you need to. Django isn't a replacement
for SQL, it's an adjunct. Particularly if you want to take advantages of
things that are very specific to one or other backend (esp. MySQL with
all the myriad of storage engine options), talking to the database is
the right idea.
You might be able to pull of something with the extra(where=) method
on a queryset, too, although that can become a bit fragile in complex
situations.

Malcolm

Not really (in a reliable way). One constraint is that Django is
designed to operate seamlessly as a WSGI application and the WSGI
specification does not permit responses to be streamed in pieces
("chunked transfer encoding" in the HTTP 1.1 parlance) from an
application.
Yes, it's theoretically possible to pass a generator to the
HttpResponse, but there are lots of technical problems that can arise.
Some of which are being worked out on the dev list at the moment, some
of which are just technically impossible (like the WSGI constraint).

You are using the word "project" to mean something that isn't clear. Could you give a small layout of the directory structure please. It's not impossible to imagine something like the problem you're describing happening depending upon import paths. Remember that when you do "from foo import models", Python first has to parse and execute the code in "foo/__init__.py", so things might not be fully constructed. But, again, it's hard to tell without concrete code. If you can construct a very small example that demonstrates the problem (like, literally, as few lines as possible. To the point that if you remove any more lines, the problem goes away) then you've got something you can put in a bug report because then other people can try to repeat the problem and diagnose it. I'm not intimately familiar with how newforms is doing imports or recommended practices over there, but if this type of problem is cropping up, it's worth knowing about it so that we can either document "don't do that" or get things fixed if possible. Again, I'm not saying that what you're seeing is a bug or necessarily a problem in Django. I don't understand the problem you're describing from the English-language version. Code speaks more clearly here, I think. Regards, Malcolm --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Problems using custom sql in manager
I've run into an issue using a manager for a model to run some custom sql. A dumbed down version of the code looks something like this: cursor = connection.cursor() # Get list of zipcodes zips = [zip.zipcode for zip in Zip_Code.objects.filter(lat__range=(min_lat, max_lat), lon__range=(min_lon, max_lon))] sql = """ SELECT id FROM Event WHERE zip_code IN %s""" cursor.execute(sql, (zips,)) The Zipcode field is a VARCHAR(10) in the database, so the zipcodes in the list are unicode strings. If I run the query this way, I get 0 results. Although If I copy the sql it generates and run it I get several results. The interesting this is if I cast the zipcode to an integer then the query works. I also tried casting each zipcode to a regular string but it also returns 0 results. So it looks like in order for the IN function to work for the MySQLdb backend it must be a list of integers. This doesn't work so well for zipcodes that begin with 0's like Burlington VT which is "05401". Is there some trick I am missing, or is this a genuine bug in the python MySQLdb module?

You're making the assumption that you can pass a list or a tuple as a parameter to the query and that the DB wrapper will magically turn it into the right thing. This isn't correct (it happens to work by accident in some cases, like integers where str(some_list) is valid SQL). You need to be passing in N parameters with something like ', '.join(["%s"] * len(params)) used to construct the placeholders.

Mario,
I'm serving through the development server , runserver, not Apache.
Also, the model is buried in django.contrib.flatpages somewhere. I
would think that James Bennett would have mentioned something about
adding to the model if it were required. I'll keep you idea in mind,
however.
Thanks again to all,
Lloyd

Re: Problems using custom sql in manager
Thanks for your quick reply. I have been searching for a long time
for good documentation on using IN and paramaters with no luck. When
it worked with a list I assumed that was correct. Could you clarify
an example of transforming a list of items into something mysqldb
would accept then executing it? I think you are saying that if I have
2 items in the list I need to manually specify:
zips = ['7', '55544']
sql = """
SELECT id
FROM Event
WHERE zip_code IN %s, %s"""
cursor.execute(sql, (zips[0], zips[1]))
and do you need to specify the parens around the params? I tried
passing in a string like '("3", "33344")' and it didn't error, but
it didn't return any results either.
