I have 3 HTML combo/drop down boxes. All of them have a distinct name and id.
On a particular event I want to get the value of all three of them.
Can any one give me a code snippet for that?
I would like to quickly retrieve the median value from a boost multi_index container with an ordered_unique index, however the index iterators aren't random access (I don't understand why they can't be, though this is consistent with std::set...).
Is there a faster/neater way to do this other than incrementing an iterator container.size() / 2 times?
Hi,
in a Model I have a CharField with choices:
class MyModel(models.Model):
THE_CHOICES=(
('val',_(u'Value Description')),
)
...
myfield=models.CharField(max_length=3,choices=THE_CHOICES
Now in the template I access an instance of MyModel:
{{ my_instance.myfield }}
Of course the gives me val instead of Value Description. How do I get the description?
Thanks in advance!
I have the following SQL query, note I want the literal value '0' in the second
field in the second SELECT statement from the ItemSale table.
How do I express this in LINQ?
I get the error message 'Invalid anonymous type member declarator'.
SELECT BranchNumber,QuantitySold
FROM Department
UNION
SELECT BranchNumber,0
FROM ItemSale
How to express the '0' in LINQ?
var unionQuery = (from dept in Department
select new
{
dept.BranchNumber,
dept.QuantitySold,
})
.Concat(from item in ItemSale
select new
{
item.BranchNumber,
0
});
I have the following code:
NSMutableDictionary *jsonObj = [parser objectWithString:json_string error:nil];
NSString *test = [[[jsonObj objectForKey:@"questions"] valueForKey:@"owner"] valueForKey:key];
but what I get back is:
(
1a19f089a2bc4ee42bff1c102c6e89b8
)
The actual value is fine, but I get those parenthesis, which show up in my string. How can I get rid of them?
I want to do something like this
$.get('/Controller/Action/', { model : null }, function(data) {});
Unfortunatelly it doesn't work. In server side the value of the model is {object}.
How do I get null?
In Javascript I can do this:
function A(x) { return x || 3; }
This returns 3 if x is a "non-truthful" value like 0, null, false, and it returns x otherwise. This is useful for empty arguments, e.g. I can do A() and it will evaluate as 3.
Does Python have an equivalent? I guess I could make one out of the ternary operator a if b else c but was wondering what people use for this.

I'm trying to query a database, and return a set of values. Part of the data i'm trying to return is an insurance premium breakdown.
Is it possible to run a query, that selects multiple fields, then adds then and returns them as a single value?
I've seen SUM() but the examples i've seen show it as adding up the results of an entire field - where as i need it to add specific fields for each row returned.
Any help is much appreciated.

Hello:
I have a simple webpage that displays the credit balance for calling cards. So far without any problems, with HTML, PHP and mysql, I was able to retrieve the balance from a data base. But I have to display the result in ANOTHER PAGE, wich looks akward because the page must reload.
Can I just load this value into a pre-drawed field under the input fields that collect the data from the customer? Such as :
Account Number: 134556
PIN: *
|send|
Balance is: $12.36
Thanks in advanced
I have a column whose value is a json array. For example:
[{"att1": "1", "att2": "2"}, {"att1": "3", "att2": "4"}, {"att1": "5", "att2": "6"}]
What i would like is to provide a view where each element of the json array is transformed into a row and the attributes of each json object into columns. Keep in mind that the json array doesn't have a fixed size.
Any ideas on how i can achieve this ?
