  • how to search values in a dictionary that is assigned to a key for a PFObject without downloading all PFObjects of that class (iOS/Parse)

    - by mkc842
    Suppose I have a set of PFObjects (essentially dictionaries) of class "myObject". Objects of this class contain for key "myDictionary" a dictionary. "myDictionary", in turn, has a key "myKey" that I want to access and search for matches against "mySearchTerm". I don't want to download all myObject objects and then iterate through them to check myKey in each, because that would be very inefficient. I want to use a findObjects message to return just the matches. Is such a query possible? In other words, how can I search the values in a dictionary that is assigned to a key for a PFObject without downloading all PFObjects of that class? Here's what it might look like if there were a simple method for it, but I made up the containsKey part to clarify what I am contemplating: PFQuery *objectQuery = [PFQuery queryWithClassName:@"myObject"]; [objectQuery whereKey:@"myDictionary" ~containsKey~:@"myKey" equalTo:"mySearchTerm"];

  • How to insert multiple check-box values inside database when one or more will be left unchecked?

    - by Sally
    I have a form that contains 5 check boxes. The user may select one or more of these check boxes. The user may select 2 and leave 3 unchecked or select 4 and leave one unchecked and so on, in that case how can I write the php/mysql code that will insert the form data into the database. With just one selection it's easy, I would do: $checkbox_value = $_POST['i_agree']; mysql_query("INSERT INTO terms (user, pass, conditions) VALUES ('$user','$pass','$checkbox_value')"); But how can I write this when there are multiple check box options and only one or more of them will be checked? I want to insert them all in one column called "tags" separated by commas.

  • PHP Included files writing their own content from Importer values ...

    - by Adrian
    Hello, I have a index.php file that will include several external files: "content/templates/id1/template.php" "content/templates/id2/template.php" "content/templates/id3/template.php" etc. All these files are loaded dynamically into index.php (it reads all folders inside "templates" directory and then includes every "template.php" file). I want to make "template.php" to have the same code in all the "id1,id2,id3" folders, BUT to load values from index.php depending in which folder it stays.. How can I do that? Thank You!

  • How to pass values from client side to server side ?

    - by manojp1988
    Hi All, I got a situation to transfer values from jsp to servlet's action class. Previously we did it using <input type="hidden" id="name" value="manoj" /> we take this value in action class by request.getParameter("name"). But now we couldn't pass value like "Hi\n i am\n Manoj". Since it has new line included in the string we couldn't take it like this to action. So how I can take value like this to action or is there any way other than hidden input? Thanks .

  • How do you stop echo of multiple values with 'foreach' in PHP?

    - by Aaron EA
    How do you when using custom fields in Wordpress echo just the first value using foreach? Currently the code is: <?php for(get_field('venue_event') as $post_object): ?> <a href="<?php echo get_permalink($post_object); ?>"><?php echo get_the_title($post_object) ?></a> <?php endforeach; ?> This takes the field from the wordpress page (the field is a link to another page), creates a link to that page using get_permalink but when I want to echo the page title it does it, but then it also echos all other values that are not needed.

  • What's the best way of using a pair (triple, etc) of values as one value in C#?

    - by Yacoder
    That is, I'd like to have a tuple of values. The use case on my mind: Dictionary<Pair<string, int>, object> or Dictionary<Triple<string, int, int>, object> Are there built-in types like Pair or Triple? Or what's the best way of implementing it? Update There are some general-purpose tuples implementations described in the answers, but for tuples used as keys in dictionaries you should additionaly verify correct calculation of the hash code. Some more info on that in another question. Update 2 I guess it is also worth reminding, that when you use some value as a key in dictionary, it should be immutable.

  • What values does Camera.Parameters.set("picture-size", ?) take?

    - by mobilekid
    Hi, my app involves some work with the camera, therefore it needs to handle capturing of images with different resolution. My targets are 1.6 - onwards. Does anyone know what to pass in the value argument for Camera.Parameters.set("picture-size", value) I have look at the Donut release of the Camera app, however, it was not very clear what exactly has been used there as the value is retrieved from the SharedPreferences. // Set picture size parameter. String pictureSize = mPreferences.getString(CameraSettings.KEY_PICTURE_SIZE, getString(R.string.pref_camera_picturesize_default)); mParameters.set(PARM_PICTURE_SIZE, pictureSize); Lookin at the strings.xml I can see that R.string.pref_camera_picturesize_default = 2048x1536, however, I'm not sure what other values can be passed there? Is it any resolution you fancy, or are they only certain resolutions the drivers can handle? Thanks.

  • Can I use SQL to update multiple rows with multiple values from another table?

    - by stu
    I've got a one to many table with ids and traits for those users. I want to copy one user's settings to another. userid trait onoff ------ ----- ----- 1 1 on 1 2 on 1 3 on 1 4 on 2 1 off 2 2 off 2 3 off 2 4 off So I want to copy the onoff values from user 1 to 2, so that user2 has everything on when I'm done. update table set onoff = (select onoff from table where userid=1) where userid=2 that's the basic idea, but obviously doesn't work. I imagine I want the server to think in terms of a correlated subquery, but the outer part isn't a query, it's an update. Is this even possible in one step?

  • Can I configure a strongly typed data set to use nullable values?

    - by Dan Tao
    If I have a strongly typed data table with a column for values of type Int32, and this column allows nulls, then I'll get an exception if I do this for a row where the value is null: int value = row.CustomValue; Instead I need to do this: if (!row.IsCustomValueNull()) { int value = row.CustomValue; // do something with this value } Ideally I would like to be able to do this: int? value = row.CustomValue; Of course I could always write my own method, something like GetCustomValueOrNull; but it'd be preferable if the property auto-generated for the column itself simply returned a nullable. Is this possible?

  • How should I declare default values for instance variables in Python?

    - by int3
    Should I give my class members default values like this: class Foo: num = 1 or like this? class Foo: def __init__(self): self.num = 1 In this question I discovered that in both cases, bar = Foo() bar.num += 1 is a well-defined operation. I understand that the first method will give me a class variable while the second one will not. However, if I do not require a class variable, but only need to set a default value for my instance variables, are both methods equally good? Or one of them more 'pythonic' than the other? One thing I've noticed is that in the Django tutorial, they use the second method to declare Models. Personally I think the second method is more elegant, but I'd like to know what the 'standard' way is.

  • ASP MVC C#: Is it possible to pass dynamic values into an attribute?

    - by wh0emPah
    Okay I'm very new to C# and i'm trying to create a little website using ASP MVC2. I want to create my own authorization attribute. but i need to pass some values if this is possible. For example: [CustomAuthorize(GroupID = Method Parameter?] public ActionResult DoSomething(int GroupID) { return View(""); } I want to authorize the access to a page. but it depends on the value passed to the controller. So the authorization depends on the groupID. Is this possible to achieve this in any way?. Thanks in advance.

  • Is it possible to raise an error if a variable assignment in a select returns multiple values?

    - by Brann
    I just found a bug on one of my softwares where I had forgotten a where clause. The code was something like that : declare @foo bigint declare @bar bigint select @foo = foo, @bar=bar from tbFooBar where (....a long list of condition goes there) (... and an extra condition should have went there but I forgot it) Unfortunately, the where clause I forgot was useful in very specific corner cases and the code went through testing successfully. Eventually, the query returned two values instead of one, and the resulting bug was a nightmare to track down (as it was very difficult to reproduce, and it wasn't obvious at all that this specific stored procedure was causing the issue we spotted) Debugging would have been a lot easier if the @foo=foo had raised an exception instead of silently assigning the first value out of multiple rows. Why is that this way? I can't think of a situation where one would actually want to do that without raising an error (bearing in mind the clauses 'distinct' and 'top' are there for a reason) And is there a way to make sql server 2008 raise an error if this situation occurs ?

  • How can I retrieve the values of controls in the form that posted?

    - by Mike at KBS
    I know this has got to be the simplest-sounding question ever asked about ASP.Net but I'm baffled. I have a form wherein my visitor will enter name, address, etc. Then I am POSTing that form via the PostBackUrl property of my Submit button to another page, where the fields are supposed to be all re-formed into new hidden fields, then POSTed again to Paypal. My problem is I cannot get at the values entered by the visitor in the original page. Any time I put in "runat='server'", ASP.Net completely changes the ID of the control, making it impossible to figure out how to access. In the POSTed form I tried Request.Form["_txtFirstName"] and that turned up null. Then I tried ((TextBox)PreviousPage.FindControl("_txtFirstName")).Text and that was null, too. I've tried variations on those. I cannot figure out how I'm supposed to get at these controls. Why does this stuff need to be so difficult?

  • How does one reduce a list of boolean values in Common Lisp?

    - by postfuturist
    Given a list of values, I want to reduce the list to T if all the elements are not NIL, NIL if not. This gives me an error: (apply #'and (get-some-list)) As does this: (reduce #'and (get-some-list)) This is the best I've come up with: [11]> (defun my-and (x y) (and x y)) MY-AND [12]> (reduce #'my-and '(T T T T T)) T [13]> (reduce #'my-and '(T T T T NIL)) NIL Why is "#'and" invalid? Is there a more idiomatic way to do this in Common Lisp?

  • Codeigniter Form Validation - how to unset form values after success?

    - by BrynJ
    I realise this request goes against the example provided in the CI documentation (which advises a separate 'success' page view), but I would like to reutilise a given form view after a form has been successfully submitted - displaying a success message then displaying a blank form. I've tried a few ways unsuccessfully to clear the validation set values (unsetting $_POST, setting rules / fields to an empty array and rerunning validatio). I could redirect to the same page, but then I'd have to set a session variable to display a success message - which is a messy approach. Any ideas how to achieve the above?

  • Python - Flatten a dict of lists into unique values?

    I have a dict of lists in python: content = {88962: [80, 130], 87484: [64], 53662: [58,80]} I want to turn it into a list of the unique values [58,64,80,130] I wrote a manual solution, but it's a manual solution. I know there are more concise and more elegant way to do this with list comprehensions, map/reduce , itertools , etc. anyone have a clue ? content = {88962: [80, 130], 87484: [64], 53662: [58,80]} result = set({}) for k in content.keys() : for i in content[k]: result.add(i) # and list/sort/print just to compare the output r2 = list( result ) r2.sort() print r2

  • SQL Server pivots? some way to set column names to values within a row

    - by ccsimpson3
    I am building a system of multiple trackers that are going to use a lot of the same columns so there is a table for the trackers, the tracker columns, then a cross reference for which columns go with which tracker, when a user inserts a tracker row the different column values are stored in multiple rows that share the same record id and store both the value and the name of the particular column. I need to find a way to dynamically change the column name of the value to be the column name that is stored in the same row. i.e. id | value | name ------------------ 23 | red | color 23 | fast | speed needs to look like this. id | color | speed ------------------ 23 | red | fast Any help is greatly appreciated, thank you.

  • How to create wordpress-like option table and get values for each row?

    - by Nacho
    Hi guys. I'm looking to create an options table in my db that makes every record a system option, so I can work with a little number of fields. My db has the following structure: 3 columns named id, name, and value The following data is inserted as an example: +--+-----------+--------------------------+ |id|name |value | +--+-----------+--------------------------+ | 1|uri |www.example.com | | 2|sitename |Working it out | | 3|base_folder|/folder1/folder2/ | | 4|slogan |Just a slogan for the site| +--+-----------+--------------------------+ That way I can include a large number of customizable system options very easily. The problem is that I don't know how to retrieve them. How do I get the value of uri and store it as a var? And better yet, how do I get, for exmaple, values of id 1 and 4 only without making a query each time? (I assume multiple queries are useless and a pretty ugly method.) I know the question is pretty basic but I'm lost here. I'd really appreciate your answer!

  • One configuration per domain name on the same application. How to easily access config values from m

    - by Aymeric
    Hi, I run a Ruby on Rails website that have multiple domain names. I have a "Website" table in the database that stores the configuration values related to each domain name: Website - domain - name - tagline - admin_email - etc... At the moment, I load the website object at the start of each request (before_filter) in my ApplicationController: @website = Website.find_by_domain(request.host) The problem is when I need to access the @website object from my models methods. I would like to avoid to have to pass @website everywhere. The best solution would be to have something similar to APP_CONFIG but per domain name. def sample_model_property - - "#{@website.name} is a great website!" end How would you do it?

  • R: What are the best functions to deal with concatenating and averaging values in a data.frame?

    - by John
    I have a data.frame from this code: my_df = data.frame("read_time" = c("2010-02-15", "2010-02-15", "2010-02-16", "2010-02-16", "2010-02-16", "2010-02-17"), "OD" = c(0.1, 0.2, 0.1, 0.2, 0.4, 0.5) ) which produces this: > my_df read_time OD 1 2010-02-15 0.1 2 2010-02-15 0.2 3 2010-02-16 0.1 4 2010-02-16 0.2 5 2010-02-16 0.4 6 2010-02-17 0.5 I want to average the OD column over each distinct read_time (notice some are replicated others are not) and I also would like to calculate the standard deviation, producing a table like this: > my_df read_time OD stdev 1 2010-02-15 0.15 0.05 5 2010-02-16 0.3 0.1 6 2010-02-17 0.5 0 Which are the best functions to deal with concatenating such values in a data.frame?

  • JQuery.ready is too late: How do I apply CSS Values with JQuery before Rendering?

    - by viatropos
    I want to be able to apply opacity to some elements to make them invisible only if javascript is enabled. I don't want to use display:none because I want the layout to act as if they're in the DOM, so setting opacity to 0 is perfect. I want to be able to set this initial value using Javascript, using JQuery, so I don't have to mess with browser differences on the opacity (and many other) attributes. But if I set opacity to 0 like so: $(document).ready(function() { $("#header").css("opacity", 0); $("#header").animate({opacity:1}, 500); }); ...half the time it's already visible on the screen, so it appears and disappears. How do I set these css values using JQuery before they ever can render?
