  • Django + Ajax

    - by Joe
    So, I am just starting to use jQuery with one of my Django projects, but I have a pretty noobie question. In a django view you have to return an HttpResponse object from the view, but sometimes I don't need to return anything. For instance, I might just be updating the database via ajax and don't need to send anything back. So my question is, what do you do in that situation? Thanks

  • Inserting Strings Without Trailing Spaces SQL

    - by Soo
    I have a database with a field named Field1 that has 100 nchars per entry. Each time I add a value, it is stored as: "value (100-ValueLength Spaces) " So Basically each stored value has a string of spaces after it. This is getting to be an issue when I try doing: if (value == "Example") because of all of the empty spaces after the string. How can I get it so the stored values don't have all of these trailing spaces?

  • Using a CSV/Text-File as a RecordSource for a Report

    - by Falcon
    I need an Access Report to use a CSV-File as a RecordSource. I have searched and tried many things, yet, I've found no way to achieve this. A temporary table in some other database is not an option. I've been trying to use a DAO RecordSet, but while I can read the RecordSet just fine I cannot set it as the report's RecordSet and I cannot use its Name as the RecordSource Property as both approaches lead to an error. Please help me find a way!

  • PHPFOG and MySql

    - by jim dif
    I am playing around with PHPFog and as a result I ended up with a MySql database. I am trying to figure out how to connect to it with a success message. PHPFog says use this: mysql_connect( $server = getenv('MYSQL_DB_HOST'), $username = getenv('MYSQL_USERNAME'), $password = getenv('MYSQL_PASSWORD')); mysql_select_db(getenv('MYSQL_DB_NAME')); So I basically plug my variables into the above? Or Do I do something different? Thanks, Jim

  • How do I create a safe local development environment?

    - by docgnome
    I'm currently doing web development with another developer on a centralized development server. In the past this has worked alright, as we have two separate projects we are working on and rarely conflict. Now, however, we are adding a third (possible) developer into the mix. This is clearly going to create problems with other developers changes affecting my work and vice versa. To solve this problem, I'm thinking the best solution would be to create a virtual machine to distribute between the developers for local use. The problem I have is when it comes to the database. Given that we all develop on laptops, simply keeping a local copy of the live data is plain stupid. I've considered sanitizing the data, but I can't really figure out how to replace the real data, with data that would be representative of what people actually enter with out repeating the same information over and over again, e.g. everyone's address becomes 123 Testing Lane, Test Town, WA, 99999 or something. Is this really something to be concerned about? Are there tools to help with this sort of thing? I'm using MySQL. Ideally, if I sanitized the db it should be done from a script that I can run regularly. If I do this I'd also need a way to reduce the size of the db itself. (I figure I could select all the records created after x and whack them and all the records in corresponding tables out so that isn't really a big deal.) The second solution I've thought of is to encrypt the hard drive of the vm, but I'm unsure of how practical this is in terms of speed and also in the event of a lost/stolen laptop. If I do this, should the vm hard drive file itself be encrypted or should it be encrypted in the vm? (I'm assuming the latter as it would be portable and doesn't require the devs to have any sort of encryption capability on their OS of choice.) The third is to create a copy of the database for each developer on our development server that they are then responsible to keep the schema in sync with the canonical db by means of migration scripts or what have you. This solution seems to be the simplest but doesn't really scale as more developers are added. How do you deal with this problem?

  • Accessing MySQL server via VPN in python

    - by user210481
    Hi I have a MySQL server that I need access through a VPN. I use MySQLdb package to access MySQL server in Python. When I can access the server without VPN, it works fine, but when I'm at certain locations, I need to connect through VPN. My computer is connected to the VPN and I can access the database through PHPMyAdmin, but MySQLdb gives me an error message: OperationalError: (2003, "Can't connect to MySQL server on 'MY_IP' (10061)") Any ideas on why it's not working? Thanks

  • converting factored number to decimal in MS SQL

    - by LS
    I need to convert a number which gives decimals in factored format in to decimals, i.e. 11.16 is 11.5 in decimal. This is because 16 is in base of 32 and 11.16 should be read as 11+16/32 = 11.5 I get 11.16 as a string and I need to change it to 11.5 as numeric in MS SQL(2005) database. Any shorter way of doing this rather than splitting strings,converting to numerics,maths,convert to string, concatenate and then convert to numeric?

  • Sort array by keys of another array.

    - by marbrun
    Hello There are 2 arrays, both with the same length and with the same keys: $a1 = [1=>2000,65=>1354,103=>1787]; $a2 = [1=>'hello',65=>'hi',103=>'goodevening']; asort($a1); The keys of a1 and a2 are id's from a database. a1 gets sorted by value. Once sorted, how can we use the same sorting order in a2? Thanks!

  • jqueryUI Slider: Setting minimum and maximum values in range from DB

    - by alexBrand
    I have a jQueryUI slider on my website that deals with price range. I have a products table in mysql that has various entries. I am using the slider to filter the results, but I need to set the minimum and maximum prices from the records in my database. Should I just generate (with php) hidden fields in my html that contain the minimum and maximum and then use jQuery to obtain them? Or is there a better way of achieving this, maybe using AJAX? Thanks

  • Java library suggestions for implementing a custom web server

    - by dexter
    I would like to create a web server that will serve/accept json files through REST. The JSON files being served will come from a database query and format the results into JSON. Any suggestions for a good java library. I have tried using Apache HTTPComponents. While maybe I can just create a servlet but I am not really allowed to install a servlet container in the server machine.

  • Merge Function In Entity FrameWork?

    - by Ahmed
    In NHibernate there is a merge function that does the following: if there is a persistent instance with the same identifier currently associated with the session, copy the state of the given object onto the persistent instance if there is no persistent instance currently associated with the session, try to load it from the database, or create a new persistent instance the persistent instance is returned Is this possible in EF? I mean this part : copy the state of the given object onto the persistent instance. And if i used ApplyCurrentValues it seemes to be as update behavior or not?

  • casting doubles to integers in order to gain speed

    - by antirez
    Hello all, in Redis (http://code.google.com/p/redis) there are scores associated to elements, in order to take this elements sorted. This scores are doubles, even if many users actually sort by integers (for instance unix times). When the database is saved we need to write this doubles ok disk. This is what is used currently: snprintf((char*)buf+1,sizeof(buf)-1,"%.17g",val); Additionally infinity and not-a-number conditions are checked in order to also represent this in the final database file. Unfortunately converting a double into the string representation is pretty slow. While we have a function in Redis that converts an integer into a string representation in a much faster way. So my idea was to check if a double could be casted into an integer without lost of data, and then using the function to turn the integer into a string if this is true. For this to provide a good speedup of course the test for integer "equivalence" must be fast. So I used a trick that is probably undefined behavior but that worked very well in practice. Something like that: double x = ... some value ... if (x == (double)((long long)x)) use_the_fast_integer_function((long long)x); else use_the_slow_snprintf(x); In my reasoning the double casting above converts the double into a long, and then back into an integer. If the range fits, and there is no decimal part, the number will survive the conversion and will be exactly the same as the initial number. As I wanted to make sure this will not break things in some system, I joined #c on freenode and I got a lot of insults ;) So I'm now trying here. Is there a standard way to do what I'm trying to do without going outside ANSI C? Otherwise, is the above code supposed to work in all the Posix systems that currently Redis targets? That is, archs where Linux / Mac OS X / *BSD / Solaris are running nowaday? What I can add in order to make the code saner is an explicit check for the range of the double before trying the cast at all. Thank you for any help.
