Portal Navigation unique list

[mr_vodka]

Hi all,

I am trying to create a sub navigation for a clients' list by using a portal.

Lets say for example I have a table where there is a customer, year, make, and model fields. I would like to implement a way so that from a find result by customer, a self join could be used in such a way to create a navigation but with unique values.

For example.

Customer Table joined to Main Table via id numbers. Customers: Bob, John, Sally

Main Table:

Record 1

Customer: John

Make: Ford

Model: Econoline

Year: 2000

Record 2

Customer: John

Make: Ford

Model: F-150

Year: 1999

Record 3

Customer: Bob

Make: Nissan

Model: Sentra

Year: 2003

----------------------------------------------------

So... If I do the intial find by customer, I will has the 2 records with Customer: John.

Now this is where I would like a navigational setup. If I do a self joining portal, I will get "Ford" twice as a field value...

Is there a way to just have it be "Ford" once?

Eventually I would like it add a button script to it, so that it popups a list of all "Fords" that "John" has. I have done this part already with a many portal.

What I am looking for is the navigation of have only one of the same value, maybe in a dropdown etc.

TY.

You can create a value list based on the related Make field, 'including all values starting from' your base Customers table. Then create an unstored calculation field of ValueListItems( Get(FileName); "yourvaluelist" ) or Substitute( ValueListItems( Get(FileName); "yourvaluelist" );

Hi, and thank you for the response. I am not sure if I was completely following you correctly...

Anyway, I have added a mock file sample to show you guys what I am talking about... it is in 7 tho.

Thanks again.

Change your make value list to be based on RT| Self Join Instance::Make and 'include only related values starting from' Retail. Then create a new global text field and format it as a menu, list, or radio button based on the make value list.

You don't need the ValueListItems field after all, but just so you know, you would need to enclose the value list name in quotes to get it to work.

Thank you very much for the help. Such a simple solution and I couldnt figure it out.

Thanks again.

A new problem.

The customer does not want it to be a value list but rather a portal that is used. So I figured that I would separate the make and model into its own Table. Since Many different customers can own the same make and model as well as, one owner owning different year cars of a particular make/model, I set up the sample like the following:

Table 1: Main Data Entry

Fields: RecordID

CustomerID

Year

PreviousOwner

Trim

KeyIDMakeModel

<<reference MakeModel: Make>>

<<reference MakeModel: Model>>

Table 2: MakeModel

Fields: CustomerID

Make

Model

c.Concat= CustomerID & Make & Model

Relationship Keying on: c.Concat = KeyIDMakeModel

I have thought about this and am not too sure how to accomplish this.

I can only have one copy of each Model/Make for each customer. That is why a concat calculation field was created. It would be ideal to match on something like this, but the problem is that since it is a calculation field, the field, KeyIDMakeModel from the Data Entry Table, only shows the first field value typed in. When that happens, it no longer becomes a valid relationship.

Example: c.Concat= MontanaFordMustang, However, KeyIDMakeModel= Ford, since that was the first value entered.

I feel that there must be an easier way of doing this, and maybe I just can not see the answer. I am uploading just a basic file based on the earlier file posting that I put up but the functionality is not the same.

I don't think you'll be able to use a portal to display unique makes related to CustomerID unless you create a Customer|Make table and have only one record created for each Customer-Make combination.
