  • JQuery: how to store records id for data from ajax query in dynamicly created html elements

    - by grapkulec
    Probably question title is rather cryptic but I will try to explain myself here so please bare with me :) Let's assume this configuration: server-side is PHP application responding for requests with data (list of items, single item details, etc.) in json format client-side is JQuery application sending ajax request to that PHP app and creating html content corresponding with received data So, for example: client requests "list of all animals with names staring with 'A'", gets the json response from server, and for every "animal" creates some html gizmo like div with animal description or something like that. It doesn't really matter what html element it will be but it has to point exactly to specific record by "containing" id of that record. And here is my dilemma: is it good solution to use "id" property for that? So it would be like: <div id="10" class="animal"> <p> This is animal of very mysterious kind... </p> </div> <div id="11" class="animal"> <p> And this one is very common to our country... </p> </div> where id="10" is of course indication that this is representation of record with id = 10. Or maybe I should store this record id in some custom made tag like <record_id>10</record_id> and leave an "id" strictly for what it was meant to be (css selector)? I need that record id for further stuff like updating database with some user input or deleting some of "animals" or creating new ones or anything that will be needed. All manipulations will be done with JQuery and ajax requests and responses will be visualized also with dynamic creation of html interface. I'm sure that somebody had to deal with that kind of stuff before so I would be grateful for some tips on that topic.

  • How does this XPATH query differentiate?

    - by Soham
    I am kind of repeating this question because mostly due to my own ignorance, I could not fully understand the innards. Given this HTML snippet <td valign=top class="tim_new"><a href="/stocks/company_info/pricechart.php?sc_did=MI42" class="tim_new">3M India</a></td> <td class="tim_new" valign=top><a href='/stocks/marketstats/indcomp.php?optex=NSE&indcode=Diversified' class=tim>Diversified</a></td> How does this XPATH //a[@class='tim_new'] differentiate between line 1 and line 2.

  • concatenating results from SQL query and NULL columns

    - by Curtis
    I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows: SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo FROM Users WHERE (CustomerNum = @CustomerNum) ORDER BY UserName I then set 'UserInfo' as the text field in the dropdownlist. This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist. Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event? Thanks

  • Can this django query be improved?

    - by Hobhouse
    Given a model structure like this: class Book(models.Model): user = models.ForeignKey(User) class Readingdate(models.Model): book = models.ForeignKey(Book) date = models.DateField() One book may have several readingdates. How do I list books having at least one readingdate within a specific year? I can do this: from_date = datetime.date(2010,1,1) to_date = datetime.date(2010,12,31) book_ids = Readingdate.objects\ .filter(date__range=(from_date,to_date))\ .values_list('book_id', flat=True) books_read_2010 = Book.objects.filter(id__in=book_ids) Is it possible to do this with one queryset, or is this the best way?

  • JPA2 adding referential contraint to table complicates criteria query with lazy fetch, need advice

    - by Quaternion
    Following is a lot of writing for what I feel is a pretty simple issue. Root of issue is my ignorance, not looking so much for code but advice. Table: Ininvhst (Inventory-schema inventory history) column ihtran (inventory history transfer code) using an old entity mapping I have: @Basic(optional = false) @Column(name = "IHTRAN") private String ihtran; ihtran is really a foreign key to table Intrnmst ("Inventory Transfer Master" which contains a list of "transfer codes"). This was not expressed in the database so placed a referential constraint on Ininvhst re-generating JPA2 entity classes produced: @JoinColumn(name = "IHTRAN", referencedColumnName = "TMCODE", nullable = false) @ManyToOne(optional = false) private Intrnmst intrnmst; Now previously I was using JPA2 to select the records/(Ininvhst entities) from the Ininvhst table where "ihtran" was one of a set of values. I used in.value() to do this... here is a snippet: cq = cb.createQuery(Ininvhst.class); ... In in = cb.in(transactionType); //Get in expression for transacton types for (String s : transactionTypes) { //has a value in = in.value(s);//check if the strings we are looking for exist in the transfer master } predicateList.add(in); My issue is that the Ininvhst used to contain a string called ihtran but now it contains Ininvhst... So I now need a path expression: this.predicateList = new ArrayList<Predicate>(); if (transactionTypes != null && transactionTypes.size() > 0) { //list of strings has some values Path<Intrnmst> intrnmst = root.get(Ininvhst_.intrnmst); //get transfermaster from Ininvhst Path<String> transactionType = intrnmst.get(Intrnmst_.tmcode); //get transaction types from transfer master In<String> in = cb.in(transactionType); //Get in expression for transacton types for (String s : transactionTypes) { //has a value in = in.value(s);//check if the strings we are looking for exist in the transfer master } predicateList.add(in); } Can I add ihtran back into the entity along with a join column that is both references "IHTRAN"? Or should I use a projection to somehow return Ininvhst along with the ihtran string which is now part of the Intrnmst entity. Or should I use a projection to return Ininvhst and somehow limit Intrnmst just just the ihtran string. Further information: I am using the resulting list of selected Ininvhst objects in a web application, the class which contains the list of Ininvhst objects is transformed into a json object. There are probably quite a few serialization methods that would navigate the object graph the problem is that my current fetch strategy is lazy so it hits the join entity (Intrnmst intrnmst) and there is no Entity Manager available at that point. At this point I have prevented the object from serializing the join column but now I am missing a critical piece of data. I think I've said too much but not knowing enough I don't know what you JPA experts need. What I would like is my original object to have both a string object and be able to join on the same column (ihtran) and have it as a string too, but if this isn't possible or advisable I want to hear what I should do and why. Pseudo code/English is more than fine.

  • I want a insert query for a temp table

  • PHP - JSON Steam API query

    - by Hunter
    First time using "JSON" and I've just been working away at my dissertation and I'm integrating a few features from the steam API.. now I'm a little bit confused as to how to create arrays. function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530'); $test = decode_url($api); var_dump($test['response']['players'][0]['personaname']['steamid']); } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $data = file_get_contents($url); $data_output = json_decode($data, true); return $data_output; } So ea I've wrote a simple method to decode Json as I'll be doing a fair bit.. But just wondering the best way to print out arrays.. I can't for the life of me get it to print more than 1 element without it retunring an error e.g. Warning: Illegal string offset 'steamid' in /opt/lampp/htdocs/lan/lan-includes/scripts/class.steam.php on line 48 string(1) "R" So I can print one element, and if I add another it returns errors. EDIT -- Thanks for help, So this was my solution: function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530,76561197960435530'); $data = decode_url($api); foreach($data ['response']['players'] as $player) { echo "Steam id:" . $player['steamid'] . "\n"; echo "Community visibility :" . $player['communityvisibilitystate'] . "\n"; echo "Player profile" . $player['profileurl'] ."\n"; } } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $json = file_get_contents($decodeURL); $data_output = json_decode($json, true); return $data_output; } Worked this out by taking a look at the data.. and a couple json examples, this returns an array based on the Steam API URL (It works for multiple queries.... just FYI) and you can insert loops inside for items etc.. (if anyone searches for this).

  • Help needed with Linq To Sql Query

    - by fearofawhackplanet
    I have the concept of valid/ordered transitions. So for example, it's not possible to move to status In progress from status Complete. Current and Next in table StatusTransition are FK (StatusType.Id). The Linq generator has created the following relations: Child Property Name: StatusTransitions1 Parent Property Name: StatusType1 Participating Properties: StatusType.Id -> StatusTransition.Next Child Property Name: StatusTransitions Parent Property Name: StatusType Participating Properties: StatusType.Id -> StatusTransition.Current I'm normally ok with Linq but I'm having difficulty getting the list of valid Next StatusTypes from the Current status. public List<StatusType> GetValidStatusTransitions(int statusId) { // trying to write something like the following // (obviously not correct) return _statusRepository .Where(s => s.Id == statusId) .Next.StatusTypes; }

  • Linq Query Giving Error

I have google'd and looked everywhere by I have no idea what it is talking about? It doesn't throw an exception. The only way I found out about this was stepping through the expression.

  • SQL query to get field value distribution

    - by Bryan Lewis
    I have a table of over 1 million test score records that basically have a unique score_ID, a subject_ID and a score given by a person. The score range for most subjects is 0-3, but some have a range of 0-4. There are about 25 possible subjects. I need to produce a score distribution report which looks like: subject_ID 0 1 2 3 4 ---------- --- --- --- --- --- 1 967 576 856 234 2 576 947 847 987 324 . . So it groups the data by subject_ID, then shows how many times a specific score value was given within that subject. Any SQL pointers to generate this would be greatly appreciated.

  • Whats the best way to send multiple variables in a query string within a URL

    - by Andy
    I have a client who is wanting to create a link which contains product codes so that his customers hit a page with just those products displayed in an attempt to increase conversion rates from affilliate sites. My question is whats the best way to send these multiple products in a single URL For example: http://www.mydomain.co.uk/bespoke-list.php?catNo=234-324-232-343 Obviously then the site would grab the codes from the string and display them... We're going to be using PHP! Thanks in advance.
