Hi, I have here a problem I''ve been working at for a little while but I can''t seem to get the error messages to appear correctly. My form looks something like this for "ModelA": [errors_for "modelA"] [form for "modelA"] [text "modelA" "fieldname1"] [text "modelB" "fieldname2"] [submit] [/form] The reason for this is I can create many modelB''s for each modelA but when I create modelA I want it to...

Hello all, I have two comboboxen, comboA is popultaed when :controller/list is retrieved first time. When comboA is selected, I want to auto-populate comboB (modelB belongs_to modelA). The population of tableC (modelC belongs_to modelB and belongs_to modelA) should not populate until a "GO" button is clicked (link_to with submit). Help? I need an example of how to filter the post @params and also how to preserve teh selections when "GO" is clicked. In my cu...

Hello, I''m using find_with_ferret to search multiple models and it works great. The trouble is I need to filter the results using :include and :conditions. I get two errors depending on the syntax I use in the search. Reading the source, I see the retrieve_records method seems to filter the :include and :conditions so that they only apply to the relevant model when searching

All, I''ve written a simple job/opportunity tracking database app via RoR. I have about 10 internal users. Sometimes 2 people will want to update the same record at more or less the same time and they collide. In particular user 1 may edit a record, then get distracted, and finally an hour later they click save. During that hour user 2 may have pulled up the record, edited it, and

Hi all, I have a question regarding the duplication of a model and it''s associations. For example, if I have ModelA and it has_many SubModelAs and has_many SubModelBs associated with it. Each of the SubModels a belongs to ModelA. Is there a quick way of copying ModelA and the structure that lays below it? In the end I''ll then end up with ModelB which is a copy of A, and it has copies of SubModelA and Su...

I am trying to run a GLMM on some binomial data. My fixed factors include 2 dichotomous variables, day, and distance. When I run the model: modelA<-glmmPQL(Leaving~Trial*Day*Dist,random=~1|Indiv,family="binomial") I get the error: iteration 1 Error in MEEM(object, conLin, control$niterEM) : Singularity in backsolve at level 0, block 1 >From looking at previous help topics,( http://tolstoy.newcastle.edu.au/R/help/02...

I use model comparison with glms without mixed effects with anova(modelA,modelB), with mixed effects glm (glmmPQL), this doesn't work. Is there a way to compare model fits with glmmPQL's?

...pertaining to random fields in general and not the RandomFields package specifically, in which case someone can set me straight. I like the versatility of the extended definition form that can be used in RandomFields. For example, specifying an isotropic exponential model with a nugget of 1 as: modelA=list("+", list("$", var=2, scale=2, list("exp")), list("$", var=1, list("nugget")) ) Ultimately I would like to work with anisotropic models (and data), and this is where I ge...

So, I have 2 models A and B that share 5 common attributes and all other attributes are different. So I wanted to extract these 5 out into one common table and use has_one, belongs_to to knit it back together. So now there are 3 tables with 1 having the shared properties, we''ll call this table C. Table A id dollar_amount Table B id quantity_on_hand Table C id version My question is,

Hi folks. If I am indexing ModelA and ModelB and I want to search both of them, I usually just pick one arbitrarily and use it for #multi_search. Is there a slicker pattern, regarding from which model to invoke #multi_search? Can it be invoked directly from the Ferret library? Has anyone put together some sort of "dummy...

Hola a todos. ¿Cómo puedo ajustar un modelo de regresión logística en el que la varianza de los errores no son iguales, sino que esta puede ser modelada por otras variables ? ¿Utilizando modelos mixtos o voy desencaminado? Gracias..
