  • Django Encoding Issues with MySQL

    - by Jordan Reiter
    Okay, so I have a MySQL database set up. Most of the tables are latin1 and Django handles them fine. But, some of them are UTF-8 and Django does not handle them. Here's a sample table (these tables are all from django-geonames): DROP TABLE IF EXISTS `geoname`; SET @saved_cs_client = @@character_set_client; SET character_set_client = utf8; CREATE TABLE `geoname` ( `id` int(11) NOT NULL, `name` varchar(200) NOT NULL, `ascii_name` varchar(200) NOT NULL, `latitude` decimal(20,17) NOT NULL, `longitude` decimal(20,17) NOT NULL, `point` point default NULL, `fclass` varchar(1) NOT NULL, `fcode` varchar(7) NOT NULL, `country_id` varchar(2) NOT NULL, `cc2` varchar(60) NOT NULL, `admin1_id` int(11) default NULL, `admin2_id` int(11) default NULL, `admin3_id` int(11) default NULL, `admin4_id` int(11) default NULL, `population` int(11) NOT NULL, `elevation` int(11) NOT NULL, `gtopo30` int(11) NOT NULL, `timezone_id` int(11) default NULL, `moddate` date NOT NULL, PRIMARY KEY (`id`), KEY `country_id_refs_iso_alpha2_e2614807` (`country_id`), KEY `admin1_id_refs_id_a28cd057` (`admin1_id`), KEY `admin2_id_refs_id_4f9a0f7e` (`admin2_id`), KEY `admin3_id_refs_id_f8a5e181` (`admin3_id`), KEY `admin4_id_refs_id_9cc00ec8` (`admin4_id`), KEY `fcode_refs_code_977fe2ec` (`fcode`), KEY `timezone_id_refs_id_5b46c585` (`timezone_id`), KEY `geoname_52094d6e` (`name`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; SET character_set_client = @saved_cs_client; Now, if I try to get data from the table directly using MySQLdb and a cursor, I get the text with the proper encoding: >>> import MySQLdb >>> from django.conf import settings >>> >>> conn = MySQLdb.connect (host = "localhost", ... user = settings.DATABASES['default']['USER'], ... passwd = settings.DATABASES['default']['PASSWORD'], ... db = settings.DATABASES['default']['NAME']) >>> cursor = conn.cursor () >>> cursor.execute("select name from geoname where name like 'Uni%Hidalgo'"); 1L >>> g = cursor.fetchone() >>> g[0] 'Uni\xc3\xb3n Hidalgo' >>> print g[0] Unión Hidalgo However, if I try to use the Geoname model (which is actually a django.contrib.gis.db.models.Model), it fails: >>> from geonames.models import Geoname >>> g = Geoname.objects.get(name__istartswith='Uni',name__icontains='Hidalgo') >>> g.name u'Uni\xc3\xb3n Hidalgo' >>> print g.name Unión Hidalgo There's pretty clearly an encoding error here. In both cases the database is returning 'Uni\xc3\xb3n Hidalgo' but Django is (incorrectly?) translating the '\xc3\xb3n' to ó. What can I do to fix this?

  • Dynamic data-entry value store

    - by simendsjo
    I'm creating a data-entry application where users are allowed to create the entry schema. My first version of this just created a single table per entry schema with each entry spanning a single or multiple columns (for complex types) with the appropriate data type. This allowed for "fast" querying (on small datasets as I didn't index all columns) and simple synchronization where the data-entry was distributed on several databases. I'm not quite happy with this solution though; the only positive thing is the simplicity... I can only store a fixed number of columns. I need to create indexes on all columns. I need to recreate the table on schema changes. Some of my key design criterias are: Very fast querying (Using a simple domain specific query language) Writes doesn't have to be fast Many concurrent users Schemas will change often Schemas might contain many thousand columns The data-entries might be distributed and needs syncronization. Preferable MySQL and SQLite - Databases like DB2 and Oracle is out of the question. Using .Net/Mono I've been thinking of a couple of possible designs, but none of them seems like a good choice. Solution 1: Union like table containing a Type column and one nullable column per type. This avoids joins, but will definitly use a lot of space. Solution 2: Key/value store. All values are stored as string and converted when needed. Also use a lot of space, and of course, I hate having to convert everything to string. Solution 3: Use an xml database or store values as xml. Without any experience I would think this is quite slow (at least for the relational model unless there is some very good xpath support). I also would like to avoid an xml database as other parts of the application fits better as a relational model, and being able to join the data is helpful. I cannot help to think that someone has solved (some of) this already, but I'm unable to find anything. Not quite sure what to search for either... I know market research is doing something like this for their questionnaires, but there are few open source implementations, and the ones I've found doesn't quite fit the bill. PSPP has much of the logic I'm thinking of; primitive column types, many columns, many rows, fast querying and merging. Too bad it doesn't work against a database.. And of course... I don't need 99% of the provided functionality, but a lot of stuff not included. I'm not sure this is the right place to ask such a design related question, but I hope someone here has some tips, know of any existing work, or can point me to a better place to ask such a question. Thanks in advance!

  • Rails: how can I access the request object outside a helper or controller?

    - by rlandster
    In my application_helper.rb file I have a function like this: def internal_request? server_name = request.env['SERVER_NAME'] [plus more code...] end This function is needed in controllers, model, and views. So, I put this code in a utility function file in the lib/ directory. However, this did not work: I got complaints about request not being defined. How can I access the request object in a file in the lib/ directory?

  • How do I track the method the user is looking at in VS 2010 IDE as an Addin

    - by Rob
    I have been wandering around the object model for VS 2010 and haven't been able to work out the best method for watching what the user is looking at in the main edit window. I know that each Class/method/property is broken down into its own . What I would ideally like is to hook to an event which says "The user has moved the cursor onto Project.Class.Method" and ideally "and is looking at line 4". Any suggestions?

  • ASP.NET MVC - View with master page, how to set title?

    - by bh213
    What is prefered way of setting html title (in head) for view when using master pages? One way is by using Page.Title in .aspx file, but that requires in master page which can mess with HTML code. So, lets assume no server side controls, only pure html. Any better ideas? UPDATE: I would like to set title in view NOT in the controller or model.

  • repo sync "CyanogenMod/android_prebuilt" size and resume capability.?

    - by james
    I'm downloading CyanogenMod-10.1 source on a low speed broadband. About 4GB of source is downloaded . In that 4GB, there is a big project "CyanogenMod/android_frameworks_base" which alone took 1GB of download without any interruption. Ok now, after 4GB of download, my internet got disconnected and I had to stop (ctrl + z) repo sync while it was downloading the project "CyanogenMod/android_prebuilt". Before I stopped repo sync the android_prebuilt got downloaded till 250MB and is at 42percent. I checked the working folder and there is a file "tmp_pack_df5CKb" of size 250MB in the path "$WORKING_DIR/.repo/projects/prebuilt.git/objects/pack/" . Then I restarted repo sync and it was downloading the android_prebuilt project. But I'm not sure if it was downloading from start or resuming from 250MB. While downloading this time , the previous "tmp_pack_df5CKb" isn't deleted and the content is being downloaded to a new file "tmp_pack_HPfvFG". I heard repo sync cannot be resumed for a project. But here, since the previous file isn't deleted I want to ask if android_prebuilt is resuming or downloading from start again? Now that my high speed internet is over (current speed 256kbps), I'm not sure if I can download the remaining ~4GB if single project is in size 500 MB.

    In Struts2 you can change the method used for execution for an action by changing the method attribute in the following line: <action name="registerVal" class="cz.vutbr.fit.pishotel.model.action.Register" method="execute"> Is it possible to change the validation method used as well, or is the validate method name hardcoded.

  • How to catch 'exceptions' for out of order execution in Workflow Foundation 4?

    - by Alex Key
    Hi, I am attempting to model a worklfow using a "WCF Workflow Service" in .net / vs 2010 that needs to handle out of order execution gracefully (but not allow it - if thath makes sense!?) For example I have 2 receive activities one called Initialize and the other called GetValue inside a FlowChart. In most cases Initialize should be called first and GetValue after (as modled in the flow chart). However if GetValue is executed before Initialize I do not want to return an "out of order" exception (although when I look at the WCF test client, I can't actually see an exception). But instead a custom exception saying something like "you must initialize first". In theory I could model this with lots of parallel activities and conditions to check if Initialized / Running / Terminated etc. But the business process I am modelling if very very similar to a state machine... except it must handle people executing things in the wrong order. Ideally I would like to catch the "out of order" exception (thought I don't think it's really an exception as such), check the 'exception' to see which function was attempted to run and then handle it. I have done some research around enabling AllowBufferedReceive. However I don't want to be able to execute out of order (I don't think), but instead give a detailed response if it does happen. I've looked at the new beta state machine template for WF 4 - but i'm not sure if it does what i'm after? I'm not sure if I have the wrong end of the stick, so any help would be greatly appreciated. [EDIT] To help clarify... Sorry it's a tricky one to explain. The standard I am trying to implement (the e-learning standard SCORM RTE) is structured like a state machine i.e. certain functions can only be executed in certain states. However the standard specifies that if the calling clients tries to execute a function that it is not meant to, then a warning should be issued... for example "you cannot use GetValue(), because you have not yet Initialized". Ideally I'd like to structure the workflow as the theoretical state machine and not need to have to use multiple if/else's to handle all the scenarios where something could be executed out-of-order. I'd like to catch a out-of-order exception (but I don't think there is such an exception - as it's not in the debugger) and rethrow it.

  • Is there a Rails authentication library which separates users from login methods?

    - by Gareth
    In my mental model of authentication, a user should be distinct from the way they log in. So for example, a User could have an associated EmailLogin (with an email/password), or they could have many (or none). Similarly they could have 0..* associated OpenIDLogin credentials. Are there any existing authentication libraries for Rails which use this method? Alternatively, is this a really terrible idea?

  • If I partition a drive connected via eSata will it show different partitions when connected via USB?

    - by jeffreypriebe
    I have an odd problem with an external drive. I'm formatting it connected to my laptop prior to connecting it to my router. The HDD enclosure has both an eSata and USB connections. Generally, I connect it via eSata to my laptop. I created my partitions and connected it to the router, but I see partition information that is different than what I created. After chasing leads concerning large HDD size, I mindlessly connected the HDD to my laptop with USB. Lo! I see the same partitions as the router. Attached are screenshots using the same program and the HDD in question. The only difference is the connection. For the first, I connected via eSata and hit "refresh" on the partition program. Then, turned off the HDD, disconnected the eSata cable, and connected via USB. Power and refresh. eSata: reports a total HDD size of 2328 GB, with four partitions (the third being 1.96TB) USB: reports a total HDD size of 280 GB, with three partitions (the third being 279 GB) Any idea why this is happening? It looks like it clearly is an issue of the 4K sector size and not playing nice with the USB enclosure. I tried it eSata and USB in Windows and Linux and it appears consistently that eSata is reporting correctly, USB incorrectly.

  • Strange Internet Connection issues

    - by Nodren
    I'm attempting to troubleshoot problems with a laptop computer(HP 8510w) while it's connected to a server of mine via Remote Desktop. I double checked all the settings on the win2k3 server for remote desktop to verify that remote desktop isn't what's causing the disconnect issues, and other people using different computers/laptops can all connect to remote desktop correctly with no issues. These problems happen specifically when the laptop is connected via wifi(several different wifi sources, so it's not an ISP issue) as well as connected via a Verizon data card. However there's no network downtime when the laptop is resting in the docking station and plugged into the network with the remote desktop server. These problems have also only recently occurred since a recent hard drive failure in which a new hard drive was purchased and the laptop had a fresh install of windows xp professional. There's no special software used on this machine, just office 2003. So my question is, what could cause two types of internet access to fail while other types do not? If it is infact related to the win2k3 server, why is this particular laptop getting disconnected when others are not and are all on at the same time?

  • Parse HTML with CSS or XPath selectors?

    - by ovolko
    My goal is to parse HTML with lxml, which supports both XPath and CSS selectors. I can tie my model properties either to CSS or XPath, but I'm not sure which one would be the best, e.g. less fuss when HTML layout is changed, simpler expressions, greater extraction speed. What would you choose in such a situation?

  • Fast find near users using PostGIS

    - by opedge
    I have 5 tables: - users - information about user with current location_id (fk to geo_location_data) - geo_location_data - information about location, with PostGIS geography(POINT, 4326) column - user_friends - relationships between users. I want to find near friends for current user, but it takes a lot of time of executing select query to know if user is a friend and after that execute select using ST_DWithin.. May be something wrong in domain model or in queries?

  • Ubuntu 12.04 suddenly cannot connect to WPA2/WPA Personal protected connection. Windows 7 can

    - by d4ryl3
    I have a laptop with Windows 7 and Ubuntu 12.04. I have a Cisco E1200 and when I set it up, it created 2 SSIDs. Let's name them: MyConnection (WPA/WPA2 personal), and MyConnection-Guest (no authentication, guest password entered via web browser). I had no problem connecting to MyConnection before, either in Windows 7 and Ubuntu. But now, I can't access MyConnection on Ubuntu. It just says "connecting..." then disconnects after a while. But I'm able to access the internet (on Ubuntu) when I connect to MyConnection-Guest. MAC filtering is off (even if it's on its MAC address is in the white list). Any idea why I'm unable to connect to MyConnection in Ubuntu? Thanks. Update: My Ubuntu installation can connect to ANY WiFi connection (WPA/WEP/no auth), except for MyConnection. Update2: This is what "The not so easy way" returned: Initializing interface 'eth1' conf '/etc/wpa_supplicant.conf' driver 'default' ctrl_interface 'N/A' bridge 'N/A' Configuration file '/etc/wpa_supplicant.conf' -> '/etc/wpa_supplicant.conf' Reading configuration file '/etc/wpa_supplicant.conf' Priority group 0 id=0 ssid='MyConnection' id=1 ssid='MyConnection' id=2 ssid='MyConnection' id=3 ssid='MyConnection' WEXT: cfg80211-based driver detected SIOCGIWRANGE: WE(compiled)=22 WE(source)=21 enc_capa=0xf capabilities: key_mgmt 0xf enc 0xf flags 0x0 netlink: Operstate: linkmode=1, operstate=5 Own MAC address: xx:xx:xx:xx:xx:xx wpa_driver_wext_set_key: alg=0 key_idx=0 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=1 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=2 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=3 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=4 set_tx=0 seq_len=0 key_len=0 ioctl[SIOCSIWENCODEEXT]: Invalid argument Driver did not support SIOCSIWENCODEEXT wpa_driver_wext_set_key: alg=0 key_idx=5 set_tx=0 seq_len=0 key_len=0 ioctl[SIOCSIWENCODEEXT]: Invalid argument Driver did not support SIOCSIWENCODEEXT wpa_driver_wext_set_countermeasures RSN: flushing PMKID list in the driver Setting scan request: 0 sec 100000 usec WPS: UUID based on MAC address - hexdump(len=16): 16 3b d8 47 9e 24 50 89 96 16 6d 66 35 f3 58 37 EAPOL: SUPP_PAE entering state DISCONNECTED EAPOL: Supplicant port status: Unauthorized EAPOL: KEY_RX entering state NO_KEY_RECEIVE EAPOL: SUPP_BE entering state INITIALIZE EAP: EAP entering state DISABLED EAPOL: Supplicant port status: Unauthorized EAPOL: Supplicant port status: Unauthorized Added interface eth1
