I have 3 tables Books, Authors and books_authors.
In Authors there is a firstname and lastname field. In the Author.php entity, I have defined function _getFullName(), but as the documentation states:
"Do bear in mind that virtual properties cannot be used in finds."
When I bake this and want to add a book, it in the BooksController function add creates:
$authors = $this->Books->Authors->find('list', ['limit' => 200,]);
to show a multiple select for the authors, but it only show the author.id in the select.
How do I get this to show the full_name in the select box?
Please only answer this, if the answer is for CakePHP version 3.
First of all you did wrong in table names the names should authors, books and authors_books.

I am building a training platform for work. I have created the requirements for a user to be trained based on a role given to them. If that role is aligned to a document it will sit against the user. I have managed to get most of the way but am struglling on the best way to finish the where statement within mysqli.
tbldocfiles is a list of my files. I am looking at docid (could be multiple files associated to the document)
tbltrainingaccess sets the roles (driver, warehouseman, customer services) and shows which role (by id) is associated to the document in docfiles.
tblusertraining is the list of users and what role they have associated to them. (driver, warehouseman, customer services).
I am listing the documents associated to the user so have thought the following is the best way:
Look at the user and how many roles he/she is allocated
Look at the roles returned in point 1 (where function)
Identify and match the documents that have the same roles as the user (Join function)
create the list, then look at the unique values for docid. (distinct value)
Example User Bri has the driver and warehouseman role.
There are 5 documents in the db, 3 of them are associated to the driver role (docid 1,2,3) and 2 of them are associated to the warehouseman role (docid 2,4) the 5th document is associayted to customerservice.
My query should do this:
List all documents associated to the roles, that are associated to the user Bri
1
2
3
2
4
Now select unique values (using docid) from the above list:
1,2,3,4.
So my answer will be a used as a count function at the end using mysql_fetch_rows
SELECT DISTINCT tbldocfiles.docid FROM tbldocfiles LEFT JOIN tbltrainingaccess ON (tbldocfiles.docid = tbltrainingaccess.docid) where groupid='1' or groupid='9'
The above code works. but i've got myself confused.
The where statement needs to be the result of a query similar to :
select * from tblusertrainingrole where userid='1' (1 will be a variable based on page selection)
the result in this would be 1, 9 which are the groupid results.
Basically any help would be appreciated! I am sure it will be simple but have burnt myself out on this for a while and most answers in here helped with joining but not the where statement (that I could find)
Thank you in advance everyone!
You can do a select statement in the where. Since it is an or statement you can use in for the results. Please replace * with the column name for the value you need. Should look like
where groupid in (select * from tblusertrainingrole where userid = '1')
I have a database with user details in one table and linked contact details in another table (where the contact details are stored as "content").
I am trying to make a quick search function where you can search for the name or any contact details. So you can either search for name or an email or phone (whatever is in the contact detail field).
This is what I have so far:
SELECT DISTINCT leads.id, CONCAT(first_name,' ', last_name) AS name
FROM `leads`
INNER JOIN `contact_details` ON contact_details`.`lead_id` = `leads`.`id`
WHERE ((CONCAT(first_name, last_name, content) LIKE ('%[XXX]%')));
This works fine. You can search for f ex "55" and it will return hits on f ex ph number 555-573-3222 or you can search for a name string like 'Joh' and it will match 'Johnson'.
My problem, though, is that regardless of what you are searching for, what is being returned is client name. Since this is for an autocomplete feature, this is obviously very confusing. If you start typing in 555-2 you want to see the suggestion 555-221-6362 not "John Johnson".
How can I return EITHER a phone number or email (from column "content") OR the concact first_name, ' ', last_name depending on whether the search matched a name or a contact_detail.content.
Since I am searching on first_name OR last_name, the search works well for "joh" matching "John" but obviously breaks when you search for "John Stan" for "John Stanley". Is there a Mysql way of fixing this or do I need to clean up string before and do alternative searches if there is a space (searching first_name AND last_name separately)
Any suggestions would be greatly appreciated as I have struggled with this for days now.
Charliez, per our comment conversation, the following is an example of how to do some nested if/thens as well as the break out of the where. You'll need to adjust this to met your specific needs, but should give you enough of an example that you should be able to get things working.
SELECT
IF(last_name LIKE '%JAM%',
last_name,
IF(first_name LIKE '%JAM%',
first_name,
''
)
) AS MatchedFieldText
FROM employee
WHERE
last_name LIKE '%JAM%'
OR first_name LIKE '%JAM%';
1) I don't think there is a way to have a SELECT statement return something different based on an OR. My first thought to solve this would be to return first, last, content and use some regex to determine if you should show the name or the number/content.
2) Kind of a hard problem, and I don't think I have seen a perfect solution to it. This might give you some ideas/put you on the right track.
I am new with MDS, and I have a question about one to many relation mapping in MDS
I have a product, contains descriptions in multiple languages. I have created two entities with derived hierarchy structure: product (P_ID, P_name)and Addtional description(P_ID, P_Name_in_German, P_name_in_English).
Additonal description is a drop down from product table from MDS UI, but I only want to populate info that releated with its same P_ID. How can I achieve that? Can I use business rules here and how it should look like?
(2012 Master data service' web interface)
I have also faced a similar problem. I have decided to add multiple fields for languages and apply business rules for them. Let's see how it would work for your entity:
Product entity
{
Code
Name
Name_in_English (text)
Name_in_German (text)
Default_language (domain based, points to Languages entity)
}
Languages entity
{
Code
Name
}
Add values to the Languages entity:
Code = "EN", Mane = "EN"
Code = "DE", name = "DE"
Now we need to add the following business rules to the Product entity:
BR1:
{
IF Condition - Equals: Default_language equals "EN"
THEN Action - Change value: Name = Name_in_English
}
BR2:
{
IF Condition - Equals: Default_language equals "DE"
THEN Action - Change value: Name = Name_in_German
}
After that You will see the product names in your product entity only in proper language which is chosen by drop-down field Default_language.
The second option:
If You want user to see only the Name field and don't want him to see additional fields,
You can hide those fields (Name_in_English and Name_in_German) by setting their width to zero.
Moreover, You can use attribute groups to separate two modes of view:
first mode (for the regular user) - You see only Code and Name
second mode (for the administrator) - You see fields: Name_in_English, Name_in_German, Default_language.
For it to work You need to create two attribute groups:
1) attribute group "EN" (add attributes Name and Code to the group)
2) attribute group "DE" (add attributes Name_in_English, Name_in_German, Default_language to the group)
Hope something of that is helpful!
You're missing something. You said you have a derived hierarchy structure but you don't show a domain based attribute on the Additional description entity with a pointer back to the Product entity. Perhaps you were thinking that the P_ID for Additional Description is the pointer back but it isn't (based on your explanation). It is the entity Code identifier for the Additional Description entity and not the key you need that points back to Product. Perhaps you meant One to One. One to Many implies you have a separate Parent_P_ID back to the Product entity.
Add the Domain Based Parent_P_ID attribute to the Additional Description entity and then reconstruct your derived hierarchy structure. This may not be that helpful because I think you have left something out of the explanation of what you are trying to do.
Hi Cocunuts,
We can not assign derived hierarchy to entities in MDS 2012,but we can achieve this in MDS 2016 , Your Domain based attribute(Drop down) cannot be further filtered in MDS 2012.
I have a simple mysql query I need to put in my admin. It shows a list of banned customers, as well as their name, notes field, and email. We have queries all over the place in this antiquated rails 2.3 app. Although I'm new to rails, I'm pretty sure this needs to live in the Customer model. I know how to build the table in the view, I'm just not sure on the syntax for the model, should it be a named scope, instance, yata yat ya...any recommendations or help would be more than welcome!
SELECT first_name, last_name, notes, email_primary
FROM customer
WHERE banned = 1
A named scope is appropriate:
class Customer
named_scope :banned, :conditions => {:banned => true}
end
Customer.banned # returns a collection of banned customers
I am trying to figure out how to have PHP check and print 2 different functions.
Both of these questions are referring to table called "remix".
The first, and more important problem at the minute, is I would like to know how to show how many DIFFERENT values are under "author", as to compile the amount of total authors registered. I need to know not only how to most efficiently use COUNT on returning UNIQUE names under "author", but how to show it inline with the total number of rows, which are currently numbered.
The second question would be asking how I would be able to set up a top 3 artists, based on how many times their name occurs in a list. This also would show on the same page as the above code.
Here is my current code:
require 'remix/archive/connect.php';
mysql_select_db($remix);
$recentsong = mysql_query("SELECT ID,song,author,filename FROM remix ORDER by ID desc limit 1;");
$row = mysql_fetch_array($recentsong);
echo'
<TABLE BORDER=1><TR><TD WIDTH=500>
Currently '.$row['ID'].' Remixes by **(want total artists here)** artists.<BR>
Most recent song: <A HREF=remix/archive/'.$row['filename'].'>'.$row['song'].'</A> by <FONT COLOR=white>'.$row['author'].'</FONT>
So as you can see, I have it currently set up to show the most recent song (not the most efficient way), but want the other things in there, such as at least the top contributor, but don't know if I would be able to put it all in one php block, break it, or be able to do it all within one quarry call, with the right code.
Thanks for any help!
I'm not sure I really understood everything in your question but we'll work this through together :p
I've created an SQLFiddle to work on some test data: http://sqlfiddle.com/#!2/9b613/1/0.
Note the INDEX on the author field, it will assure good performance :)
In order to know how to show how many DIFFERENT values are under "author" you can use:
SELECT COUNT(DISTINCT author) as TOTAL_AUTHORS
FROM remix;
In order to know the total number of rows, which are currently numbered you can use:
SELECT COUNT(*) as TOTAL_SONGS
FROM remix;
And you can combine both in a single query:
SELECT
COUNT(DISTINCT author) as TOTAL_AUTHORS,
COUNT(*) as TOTAL_SONGS
FROM remix;
To the top 3 subject now. This query will give you the 3 authors with the greatest number of songs, first one on top:
SELECT
author,
COUNT(*) as AUTHOR_SONGS
FROM remix
GROUP BY author
ORDER BY AUTHOR_SONGS DESC
LIMIT 3;
Let me know if this answer is incomplete and have fun with SQL !
Edit1: Well, just rewrite your PHP code in:
(...)
$recentsong = mysql_query("SELECT COUNT(DISTINCT author) as TOTAL_AUTHORS, COUNT(*) as TOTAL_SONGS FROM remix;");
$row = mysql_fetch_array($recentsong);
(...)
Currently '.$row['TOTAL_SONGS'].' Remixes by '.$row['TOTAL_AUTHORS'].' artists.<BR>
(...)
For the top3 part, use another mysql_query and create your table on the fly :)
